# **Defold 1.14.1**

## **Disclaimer**

This is a BETA release, and it might have issues that could potentially be disruptive for you and your team’s workflow. Use with caution. Use of source control for your projects is strongly recommended.

## **Access to the beta**

Download the editor or bob.jar from GitHub: [Release v1.14.1 - beta · defold/defold · GitHub](https://github.com/defold/defold/releases/tag/1.14.1-beta)

## ⚠ Breaking changes

From this version, we’ve set the OpenGLES 2 and WebGL 1 shaders as **opt-in**.  
We do this in order to more easily push newer shader features (like vector fonts)

You can toggle the settin `Exclude GLES 2.0` in the game.project` if you need to enable it again.

## **Beta notes:**

This version contains a number of breaking changes:

## Engine

**NEW** : ([#13048](https://github.com/defold/defold/pull/13302)) **‘Add support for Draco/Meshopt compressed glTF files’** by JCash, vlaaad  
This adds support for reading compressed glTF files, it does not yet add compression support in the engine runtime.

**NEW** : ([#9934](https://github.com/defold/defold/pull/13332)) **‘Remove GLFW2 from mobile and web backends’** by AGulev  
Build the Android, iOS, and HTML5 backends directly into `engine/platform`, using the existing Defold-maintained implementation. Remove the external GLFW2 sources and packages. Desktop platforms continue to use GLFW3.

**NEW** : ([#9320,#12970](https://github.com/defold/defold/pull/13356)) **‘Add input source to on\_input actions’** by AGulev  
Expose `action.source` in script and GUI input callbacks so games can distinguish physical mouse clicks from clicks simulated by touch, including the initial press.

`action.source` is a hash of `keyboard`, `text`, `mouse`, `touch`, `gamepad`, or `accelerometer`.

```lua
-- Bind Mouse Button Left to "click".
function init(self)
    msg.post(".", "acquire_input_focus")
end

function on_input(self, action_id, action)
    if action_id == hash("click") and action.pressed then
        if action.source == hash("mouse") then
            print("Physical mouse click")
        elseif action.source == hash("touch") then
            print("Click simulated by touch")
        end
    end
end

```

⚠ This fix makes changes to `Info.plist`. If you use a custom one for iOS, please update it by adding:

```lua
<key>UIApplicationSupportsIndirectInputEvents</key>
<true/>

```

**NEW** : ([#12335](https://github.com/defold/defold/pull/13364)) **‘Add OpenAPI discovery for runtime debug services’** by AGulev  
Adds `GET /openapi.json` to debug/headless engines so tools can discover the endpoints, parameters, request bodies, and responses supported by the engine and native extensions. The document reflects the currently registered handlers. The engine prints the full OpenAPI URL at startup, using its actual address and assigned port.

`dmWebServer::AddHandler` now requires an OpenAPI Paths Object as its fourth argument. The `const char*` JSON string is retained without copying and must remain unchanged and valid until handler removal or server destruction. A static array with a C++ raw string literal keeps the JSON readable:

```cpp
static const char EXAMPLE_OPENAPI[] = R"json(
{
  "/example": {
    "get": {
      "summary": "Get extension status",
      "responses": {
        "200": {
          "description": "OK",
          "content": {
            "text/plain": {
              "schema": { "type": "string" }
            }
          }
        }
      }
    }
  }
}
)json";

dmWebServer::HandlerParams handler_params;
handler_params.m_Handler = MyHandler;
handler_params.m_Userdata = context;
dmWebServer::Result result = dmWebServer::AddHandler(
    server, "/example", &handler_params, EXAMPLE_OPENAPI);

```

**NEW** : ([#13369](https://github.com/defold/defold/pull/13333)) **‘Add graphics backend selection for windows’** by Jhonnyg  
The windows graphics backend can now be selected via the app manifest. Supported backends are: OpenGL (default), Vulkan and DirectX12.

**NEW** : ([#10039](https://github.com/defold/defold/pull/13409)) **‘Optimize default particlefx format’** by Jhonnyg  
Use normalized RGBA8 colors in builtin particle materials, reducing vertex sizes from 40→28 bytes and 44→32 bytes for paged atlases—a 30% and 27% reduction.

This also reduces the time spent generating particle vertices by about 94–95% in our 200k-particle benchmark (on a M1 Pro/Metal): from 40.5→2.4 ms for standard materials and 52.5→2.5 ms for paged materials. Total frame time, including the remaining simulation and rendering work, drops from 48.7→10.1 ms and 60.8→10.5 ms respectively.

**NEW** : ([#3178](https://github.com/defold/defold/pull/13428)) **‘Optimize the game object transform updates’** by JCash  
Reduces CPU time spent updating game object transforms and animations. In the 100k-object benchmarks, transform-plus-animation time was 1.17×–3.25× faster than 1.14.0 with the matching animation-capacity fix. The 100k-bunny Metal scene improved from 1.743 to 1.495 ms/frame (1.17× faster).

Whole-frame improvements depend on the project: the hierarchy benchmarks improved 2.59×–2.72×. Bunnymark’s whole-frame median changed from 12.472 to 12.152 ms (1.03×); its trial ranges overlap, so this small gain is less conclusive.

**NEW** : ([#8454](https://github.com/defold/defold/pull/13423)) **‘Change gain and pan for individual sound voices’** by britzl  
It is now possible to change the sound gain and pan for individual voices:

```lua
local id = sound.play("#sound")
...
sound.set_gain("#sound", 0.4, { play_id = id })
sound.set_pan("#sound", -0.5, { play_id = id })

```

**NEW** : ([#13484](https://github.com/defold/defold/pull/13497)) **‘Fix Android gamepad GUIDs, mappings and duplicate button presses’** by JCash  
Android gamepads could be detected while their mapped controls were missing, incorrect. This fix aligns Android controller GUIDs and raw packets with SDL, consumes handled controller keys to prevent Android navigation fallback events, and provides automatic mappings for controllers without a database entry, such as the Bluetooth 8BitDo Ultimate 2C Wireless. Legacy gamepad bindings remain supported.

**NEW** : ([#13457](https://github.com/defold/defold/pull/13511)) **‘Send resize events after iOS orientation transitions’** by AGulev  
Send `window.WINDOW_EVENT_RESIZED` after iOS orientation transitions, including 180° landscape rotations that preserve window size and safe-area insets. Native extensions can use this event to refresh reserved-region geometry when a notch or Dynamic Island moves between sides.

**NEW** : ([#13431](https://github.com/defold/defold/pull/13514)) **’ Fix landscape-only games on iPhone Duo’** by AGulev  
Prevent landscape-only games from entering letterboxed compatibility mode on iPhone Duo by applying the game’s orientation restrictions at runtime.

Orientation is controlled as before through the Display settings in `game.project`:

- With **Dynamic Orientation** unchecked, **Width** and **Height** determine the orientation: landscape when width exceeds height, otherwise portrait.
- With **Dynamic Orientation** checked, the game supports both portrait and landscape.

⚠ **Projects using a custom iOS `Info.plist` must update its orientation entries to match the new built-in template to receive this fix.** Keep portrait and landscape in the UIKit orientation arrays, and move the generated game orientation list into the new key:

```xml
<key>DefoldSupportedInterfaceOrientations</key>
<array>
    {{#orientation-support}}
    <string>UIInterfaceOrientation{{.}}</string>
    {{/orientation-support}}
</array>

```

Projects using the built-in plist receive this update automatically.

**NEW** : ([#11812](https://github.com/defold/defold/pull/13522)) **‘Add configurable iOS Home Indicator modes’** by AGulev  
Adds `ios.home_indicator_mode` to `game.project`, allowing games to use a single swipe to return Home while preserving the existing two-swipe behavior by default.

**NEW** : ([#9887](https://github.com/defold/defold/pull/13523)) **‘Add resource loading timings to the profiler’** by JCash  
Resource loading can span worker threads, dependencies, and several frames, making slow resources difficult to identify. This adds per-resource loading logs and a **Show load times** button in the resource profiler, with sortable **Load** , **Preload** , **Read** , and **Create** columns in milliseconds.

Enable profiling before launching the project to measure startup loads:

```ini
[resource]
profile = 1

```

Each completed or failed load logs its total and stage timings at INFO level. Click **Capture** , then **Show load times** to inspect retained measurements for loaded resources. An em dash indicates that no completed measurement is available.

**NEW** : ([#13509](https://github.com/defold/defold/pull/13527)) **‘Add window.get\_reserved\_areas for iOS and Android’** by AGulev  
Adds `window.get_reserved_areas()` so games can position content around camera cutouts and the Dynamic Island. Supported on iOS 27.1+ and Android 9+; unsupported platforms return an empty table.

![CleanShot 2026-10-21 at 17 18 15@2x](https://github.com/user-attachments/assets/61142cf8-e65a-4368-87be-aa0c2358c3b4)

The API returns an array of `{ x, y, width, height }` rectangles in window pixels, with a bottom-left origin matching `window.get_size()`. Query during initialization and after `WINDOW_EVENT_RESIZED`. Once queried, changes to reserved areas also trigger this event when the window size stays unchanged.

```lua
function init(self)
    self.reserved_areas = window.get_reserved_areas()

    window.set_listener(function(self, event, data)
        if event == window.WINDOW_EVENT_RESIZED then
            self.reserved_areas = window.get_reserved_areas()
        end
    end)
end

```

Folds, system bars, keyboards, and gesture areas are excluded. Use `window.get_safe_area()` when a safe layout rectangle is needed.

**NEW** : ([#8040](https://github.com/defold/defold/pull/13528)) **‘Add HTML5 pixel ratio limits’** by AGulev  
Adds minimum and maximum pixel ratios for HTML5 rendering. Games can cap rendering resolution on dense displays or enable supersampling without changing the canvas’s displayed size.

Enable High DPI and configure the limits in `game.project`. This example caps rendering at 1.5 canvas pixels per CSS pixel:

```ini
[display]
high_dpi = 1

[html5]
min_pixel_ratio = 0
max_pixel_ratio = 1.5

```

Both limits default to `0`, which disables that bound. Fractional values below `1` are supported. With High DPI disabled, the rendering ratio remains `1`.

**FIX** : ([#13005](https://github.com/defold/defold/pull/13005)) **‘Improved PBR support for glTF models’** by JCash, vlaaad, matgis  
You can now expand glTF and GLB files in the Assets view to browse their meshes, materials, and images. The editor uses the file’s defined materials and textures when previewing the model, and you can preview or copy individual meshes as Model resources.

When assigning a glTF/GLB file or selecting one of its meshes in a Model component, the editor can automatically assign the corresponding materials and textures. These generated materials use our builtin `gltf.vp` and `gltf.fp` shaders. Custom materials can still be used without this dependency.

Editor scripts can use the new `editor.resource_children()` function to enumerate resources contained inside files such as glTF and GLB. Previously, it was possible to do this reliably with `editor.get('/', 'children')` while checking if every child is a directory, but now file resources may have children too.

### 

**FIX** : ([#9411](https://github.com/defold/defold/pull/13351)) **‘Fix stale touch movement deltas’** by AGulev  
After a touch moves, HTML5 builds can keep reporting nonzero `touch.dx` and `touch.dy` on later frames even when the position stays unchanged. Consume each touch delta once so frames without a new event report zero movement.

**FIX** : ([#10264](https://github.com/defold/defold/pull/13358)) **‘Fix Firefox multitouch movement deltas’** by AGulev  
Fixes touch `dx`/`dy` and `screen_dx`/`screen_dy` reporting zero when two fingers move simultaneously in Firefox HTML5 builds. Duplicate touch events previously overwrote pending movement with zero; deltas now reflect the total movement since the previous input read.

**FIX** : ([#12755,#12753](https://github.com/defold/defold/pull/13366)) **‘Fix HTML5 heap overflow and profiler server sleep’** by AGulev  
HTML5 heap sizes of 2048–4096 MiB now convert to bytes without overflowing.  
The Profiler “Server Sleep” project setting now controls Remotery’s update delay, while an explicit Remotery-specific setting retains precedence.

**FIX** : ([#13321](https://github.com/defold/defold/pull/13321)) **’ Add native Lua DAP debugger to debug engines’** by AGulev  
Adds a native DAP server so external debugger clients can attach to Defold projects running Lua 5.1 or LuaJIT. Supports breakpoints, stepping, variable inspection, evaluation, and editing across script contexts and coroutines.

The listener is disabled by default. To enable it and wait for client configuration before running startup scripts:

```sh
dmengine --config=debugger.enabled=1 --config=debugger.port=8172 --config=debugger.wait=1

```

Connect a DAP client to `127.0.0.1:8172`. The bind address is configurable through `debugger.address`.

A running project can also enable the listener through `debugger.start([port [, address]])`:

```lua
local port = debugger.start(0)

```

Passing `0` selects an available port. The call returns the listening port immediately, allowing attachment without restarting or pausing the project.

**FIX** : ([#13341,#10276](https://github.com/defold/defold/pull/13379)) **‘Use native color space for OpenGL on OSX’** by Jhonnyg  
Explicitly set the OpenGL window’s color space to sRGB so macOS displays rendered colors consistently with Metal and Vulkan. This fixes the brighter appearance of sRGB images.

**FIX** : ([#13389](https://github.com/defold/defold/pull/13389)) **‘Fix HTML5 startup stalls and reduce loader overhead’** by AGulev  
HTML5 startup could stall when `GameArchiveLoader.MAX_CONCURRENT_XHR` was configured and a single archive file contained more pieces than that limit. For example, with the default 2 MiB pieces and a concurrency limit of two, an archive file larger than 4 MiB could finish downloading but never signal completion. The default uncapped download mode was unaffected.

This change fixes completion tracking, removes duplicate archive buffers after filesystem preload, and skips WebGPU probing for WebGL-only builds.

**FIX** : ([#13391](https://github.com/defold/defold/pull/13391)) **‘Added model and render optimizations’** by JCash

- Reduce CPU work when rendering large numbers of models, especially repeated static models.
- Reduce duplicate custom vertex buffers for compatible instanced models.
- Reduce render-list processing costs when entries are already ordered.

**FIX** : ([#13416](https://github.com/defold/defold/pull/13416)) **’ Fix HTML5 sound exhaustion when the audio clock stalls’** by AGulev  
Web Audio can report `running` while its clock stops advancing, leaving the output queue full and preventing sound instances from completing. Detect this condition and switch to silent processing so instances can finish while audio recovery is retried.

It should prevent errors such as:

```lua
"DEFOLD:ERROR:GAMESYS: A sound could not be played since all sounds instances are used...

**FIX** : ([#13429](https://github.com/defold/defold/pull/13429)) **‘Optimize sprite quad vertex generation’** by JCash  
Sprite rendering spends less CPU time generating vertices by preparing shared attributes once per batch and writing standard quad vertices directly. This reduces the cost of drawing large collections of sprites.

**FIX** : ([#10929](https://github.com/defold/defold/pull/13434)) **‘Mismatched skinned model with non-skinned material produces build errors’** by Jhonnyg, vlaaad, matgis  
Mixing skinned materials with non-skinned causes crashes in runtime for certain graphics adapters (e.g Metal). Since this combination is not supported by the engine, we now produce a build error instead.

**FIX** : ([#13436](https://github.com/defold/defold/pull/13438)) **‘Fix HTML5 render target resize abort with depth/stencil attachments’** by ekharkunov  
Fixed an HTML5 crash when resizing a render target that has a depth or depth+stencil buffer with `render.set_render_target_size`. This affected both render targets created with `render.render_target()` and `.render_target` resources.

**FIX** : ([#13446](https://github.com/defold/defold/pull/13452)) **‘Reject render targets without attachments’** by Jhonnyg  
Render targets resources and runtime created render targets without any attachments are now rejected. In some cases where you might want to use a “dummy” render target resource that is modified an recreated in runtime, you will have to create at least one attachment (color or depth/stencil) that is at least 1x1 in size. This is to prevent and simplify logic around using invalid render targets in the engine.

**FIX** : ([#12748](https://github.com/defold/defold/pull/13453)) **‘Defer startup resize messages until the render socket exists’** by Jhonnyg  
Fixes an issue where the engine posts resize messages to the render socket before the renderer exists. This currently happens when using the Vulkan graphics adapter on some platforms.

**FIX** : ([#13408](https://github.com/defold/defold/pull/13454)) **‘Avoid misleading OpenGL depth/stencil storage warnings’** by Jhonnyg  
Fixed an incorrect warning emitted from the OpenGL adapter related to render targets with depth texture attachments. Previously, if you create a render target resource and check the “depth texture” property, this warning would always be emitted even though there are no exposed stencil parameters in the render target resource UI:

`Creating a RenderTarget with different backing storage, defaulting to the depth buffer type for both.`

**FIX** : ([#13447](https://github.com/defold/defold/pull/13455)) **‘Fix creating runtime Vulkan render targets without color attachments’** by Jhonnyg  
Fixed an issue where creating dynamic render targets via render scripts that has depth attachments but no color attachments will crash the engine.

**FIX** : ([#13470](https://github.com/defold/defold/pull/13470)) **‘Upload the shared GUI vertex buffer once per world’** by AGulev  
GUI scenes in the same world previously re-uploaded the growing shared vertex buffer after each scene. Upload the completed buffer once per frame to avoid redundant transfers when rendering multiple GUI scenes.

**FIX** : ([#13469](https://github.com/defold/defold/pull/13469)) **‘Add a render item API to dmSDK’** by JCash  
Adds a persistent render item API for C++ rendering integrations. Engine components now reuse renderer-owned handles instead of allocating and rebuilding render-list entries every frame. Items support enable/disable, transforms, materials, batch keys, and sphere, AABB or OBB bounds.

**Note** ⚠: The legacy render-list API (`RenderListAlloc()`, `RenderListSubmit()` and `RenderListMakeDispatch()`) is deprecated. Existing integrations continue to work, with a one-time warning from each deprecated API.  
It will still work for a short period of time, until the next major release.

### Usage

- Create the `HRenderItemDispatch` information when creating the component world.
- For each component/renderable item, create a new `HRenderItem`
- Update the render item data when the information changes
- Delete the render item/dispatch when their represented objects are destroyed

```cpp
#include <dmsdk/render/render.h>

dmRender::HRenderItem item = dmRender::NewRenderItem(context, dispatch, user_data);
dmRender::SetMaterial(context, item, material);
dmRender::SetWorldTransform(context, item, world_transform);
dmRender::SetBoundingOBB(context, item, local_min, local_max);
dmRender::Enable(context, item, true);
// Each frame, between RenderListBegin() and RenderListEnd():
dmRender::SubmitRenderListDispatch(context, dispatch);

```

**FIX** : ([#6272](https://github.com/defold/defold/pull/13472)) **‘Improved .buffer runtime format storage’** by JCash, vlaaad  
We’ve replaced the generic data storage to a packed runtime format that is smaller on disc and also loads faster as we can map it 1:1 at runtime.

**FIX** : ([#13473](https://github.com/defold/defold/pull/13473)) **‘Avoid redundant debug geometry uploads’** by AGulev  
Debug geometry was uploaded before every render-list pass, including passes that did not draw it. Upload it when first needed, then reuse the buffer across subsequent passes until the geometry changes.

**FIX** : ([#11729](https://github.com/defold/defold/pull/13482)) **‘Strip unused Ogg Vorbis metadata during builds’** by AGulev, matgis  
Ogg Vorbis files with large metadata, such as embedded cover art, can exceed the decoder’s initial header buffer and fail to play. Bob and the Editor now strip this metadata when building `.oggc` files, preserving the encoded audio and source assets.

**FIX** : ([#13439](https://github.com/defold/defold/pull/13489)) **‘Fix Windows taskbar icon during slow startup’** by AGulev  
Use the executable’s icon as the taskbar fallback when slow startup blocks Windows icon requests. This prevents the generic icon from appearing with either the default icon or a custom `windows.app_icon`.

**FIX** : ([#8250](https://github.com/defold/defold/pull/13491)) **‘Defer GUI layout notifications until initialization completes’** by AGulev  
GUI scripts could receive `layout_changed` before `init()` when a window resize occurred while a collection proxy was loading. Layout changes now apply immediately, while notifications before or during initialization are combined and delivered after `init()` succeeds.

**FIX** : ([#13504](https://github.com/defold/defold/pull/13516)) **‘Fix crashes when GUI text starts with a UTF-8 continuation byte’** by JCash  
GUI text that starts with a stray UTF-8 continuation byte no longer triggers an array-capacity assertion or writes past the codepoint array. The converter grows the array when necessary and returns the actual number of decoded codepoints.

**FIX** : ([#13501](https://github.com/defold/defold/pull/13501)) **‘Replace VP8 recording with native MP4 capture’** by AGulev  
Replace the VP8/IVF recorder with H.264 MP4 recording for desktop debug engines. Games can control recording through a new Lua module, while external tools can use the engine HTTP service. Supported macOS and Windows versions can also capture application audio; Linux records video only.

Start recording from a script with a writable output path:

```lua
local ok, err = recorder.start({
    path = sys.get_save_file("my_game", "capture.mp4"),
    fps = 30,
    audio = false,
}, function(self, event, result)
    if event == recorder.EVENT_STARTED then
        print("Recording started")
    elseif event == recorder.EVENT_STOPPED then
        print("Saved:", result.path)
    elseif event == recorder.EVENT_ERROR then
        print(result.error)
    end
end)
if not ok then print(err) end

```

Call `recorder.stop()` after `EVENT_STARTED` to request finalization. The file is ready when the callback receives `EVENT_STOPPED`. Lua audio capture defaults to false; set `audio = true` on supported platforms.

**FIX** : ([#13526](https://github.com/defold/defold/pull/13526)) **‘Add Metal GPU trace capture to the engine service’** by JCash  
Debug builds on macOS can now capture Metal GPU traces through the engine service at `/profiler/gputrace`, without a native extension. The resulting `.gputrace` files can be inspected in Xcode or by using `gpudebug`.

### For the agent

Launch the engine with the Metal graphics adapter and `METAL_CAPTURE_ENABLED=1`. Set `ENGINE` to the engine service address printed in the log and use a writable absolute path that does not already contain a trace:

```sh
ENGINE=http://127.0.0.1:8001
curl -fsS -X POST -H 'Content-Type: application/json' \
  --data '{"path":"/tmp/frame.gputrace","frames":1}' \
  "$ENGINE/profiler/gputrace"
curl -fsS "$ENGINE/profiler/gputrace"

```

`POST` schedules a capture; poll `GET` until it completes or fails. `DELETE` cancels a pending capture or stops an active capture after the current rendered frame. The endpoint is listed in `/openapi.json` only on macOS, and returns HTTP 501 when Metal capture is unavailable.

**FIX** : ([#13534](https://github.com/defold/defold/pull/13538)) **‘Reduced amount of temporary allocations when receiving a large http response’** by britzl  
This change reduced memory usage when receiving an http response. The response buffer is sized according to the value provided in the `Content-Length` header. If the response has `Transfer-Encoding` set to `chunked` the `Content-Length` header is ignored and the response buffer will resize as more data is received. Instead of growing the response buffer in fixed increments the response buffer will now double in size each time it has to be resized. This may significantly reduce temporary allocations while receiving a large response.

**FIX** : ([#13503](https://github.com/defold/defold/pull/13503)) **‘Added emoji support to fonts’** by JCash  
Vector fonts now render colored emojis through Slug in Labels and GUI text, including palette colors and linear/radial gradients. Color rendering is limited to Vector fonts.

To add emojis to an existing font, use **Dynamic** glyph generation, **Vector** mode and the matching built-in Vector material. Enable **Use full text layout system** in the App Manifest and **Shader → Exclude GLES 2.0** in `game.project`.

Copy an emoji font (COLRv1) to `fonts/NotoColorEmoji-Regular.ttf` in your project. Include it in the bundle through **game.project → Project → Custom Resources** (append to any existing entries):

```ini
[project]
custom_resources = /fonts/NotoColorEmoji-Regular.ttf

```

The Lua path alone does not include the font in the bundle. Once bundled, add it to your existing font from Lua (Label example):

```lua
function init(self)
    local font_resource = go.get("#label", "font")
    font.add_font(font_resource, "/fonts/NotoColorEmoji-Regular.ttf")
    label.set_text("#label", "Hello 😀 🍎 🚀")
end

```

For a GUI text node named `text`, use this in its `.gui_script`:

```lua
function init(self)
    local node = gui.get_node("text")
    local font_resource = gui.get_font_resource(gui.get_font(node))
    font.add_font(font_resource, "/fonts/NotoColorEmoji-Regular.ttf")
    gui.set_text(node, "Hello 😀 🍎 🚀")
end

```

Call `font.add_font` once per shared font resource. Ordinary text continues using the original font.

**FIX** : ([#3736,#12831,#12684](https://github.com/defold/defold/pull/13556)) **‘Optimized resource loader scheduling with our job system’** by JCash  
We’ve updated our resource loader to more efficiently use a shared dependency graph together with the job system.  
This simplifies the code, and keeps number of resource specific threads down to a minimum.

Native resource updates can return `RESULT_PENDING` during PostCreate or an ongoing recreation, including reload notifications. No update is applied in that case; retry after the operation returns.

**BREAKING CHANGE** : ([#13543](https://github.com/defold/defold/pull/13543)) **‘Exclude GLES 2.0 shaders by default’** by Jhonnyg  
Enable `Exclude GLES 2.0` in game.project files by default, skipping shader compilation for OpenGL ES 2.0 and WebGL 1.0.

⚠ BREAKING CHANGE ⚠

This means that current projects that target ES2 and WebGL1 will need to uncheck this setting (if not previously changed). ES2 / WebGL1 is now considered opt-in rather than opt-out.

**NEW** : ([#13047](https://github.com/defold/defold/pull/13263)) **‘Added .ktx2 support for .gltf files’** by JCash, vlaaad  
Adds support for `.ktx2` textures. They are often used by `.gltf`/`.glb` files.

Texture profiles control the compiled output. Either choose “Keep KTX2 Format” or select the format you wish to recompress to.

**Note:** Note that this may apply another lossy compression! For best result on all platforms, make sure your original `.ktx2` format supports the platforms you are using/targeting.

**NEW** : ([#10665](https://github.com/defold/defold/pull/13412)) **’ Support arbitrary tile source animation frames’** by AGulev  
Tile source animations can now use individual tiles in any order, including repeated tiles, without rearranging the source image. The new **Frames** property replaces **Start Tile** and **End Tile** and accepts comma-separated tile numbers and inclusive ranges in either direction, such as `1, 3-5, 8, 3` or `4-2`.

The editor displays consecutive runs of at least three frames as ranges: `1, 2, 3` becomes `1-3`, and `3, 2, 1` becomes `3-1`. Pairs stay as `1, 2` or `2, 1`; frame order and repetitions are preserved.

Editor scripts read and write `frames` as a Lua array of integers through `editor.get()`, `editor.tx.set()`, and `editor.tx.add()`:

```lua
editor.transact({
    editor.tx.add("/main/character.tilesource", "animations", {
        id = "walk",
        frames = {1, 3, 4, 5, 8, 3},

 ![image](https://github.com/user-attachments/assets/82204abf-8878-4bb7-a40d-e5c7511e5c6b)

This feature allows us to render text with sharp features, by utilizing vector graphics.  
Another benefit is that It also uses less texture resources.

The vector algorithm chosen was [Slug](https://github.com/EricLengyel/Slug).

Along with this feature, we also made the available settings for fonts much more dynamic, allowing for better developer control.

## Outline/Shadow Bitmap Size

Since the vector graphics doesn’t lend itself to performant rendering of outlines or shadows, we’re still using bitmap rasterization (SDF) for these features. it affects the texture memory being used.

This also affects shadows, which are now a rasterized `gaussian blur` which makes it much smoother than before.

The font property name is `Outline/Shadow Bitmap Size`

- Vector fonts:
  - The size of the bitmaps are taken from the `.font` in this case
  - If no outline/shadow is configured, the `Outline/Shadow Bitmap Size` property of the .font is read-only (default 15)

- SDF Font:
  - The size is used as before, to generate the SDF bitmaps

- Bitmap fonts, the font size property is read-only, as it is inferred from the `.fnt` file.

## Mode

- `SDF` - Select this for the old sdf rendering pipeline. Uses `label-df.material`
- `Vector` - Uses the vector graphics rendering. Uses `label-vector.material`

## Glyph generation

- `Static` generation means that all the glyphs are generated during the build of the game. The `Characters` field of the .font files is used to populate the textures. The source `.ttf`/`.otf` won’t be bundled with the game.

- `Dynamic` generation means that the glyphs are generated at runtime. When loading such a font, it uses the `Prewarm text` property to do text shaping in order to load the correct glyphs. The source `.ttf`/.otf will be bundled with the game.

## Migration

The idea is that it should not affect existing project, they’ll still use the `SDF` rendering if that’s what they’ve chosen.

If you create new `.font` files though, they’ll default to the `Vector` rendering.  
Switching between the two modes is only a few steps:

- Select `Mode` → `Vector`
- Select `Glyph generation` → `Dynamic`

## Feature Support

This implementation uses shader features that are not available for `WebGL1` or `GLES 2`.  
The feature requires texture formats `RGBA16F` and `R32UI`. There is no automatic SDF fallback for unsupported devices.

**FIX** : ([#11688](https://github.com/defold/defold/pull/13425)) **’ Report missing DLL launch failures’** by AGulev, vlaaad
