Adding a 3rd texture to sprites causes a crash

andrew-flick · April 23, 2024, 1:30pm

I have already got 2 texture atlases. One for the front of cards and one for the back which works fine. I’m now trying to add a 3rd for the normals and I get a crash…

I’m not sure what I have done wrong to cause this.

The best you can do in such cases is try to isolate the crash in a separate small project, and then open an issue on the GitHub issue tracker (using Help > Report Issue). Explain the problem there and attach your repro project to the issue + console log as a code block or just a txt file.

It will help us to track the issue. Using Help > Report Issue provides most of the information we need. A repro case will help us to figure out what’s going on and fix the issue as soon as possible.

I have uploaded a repro project for you to take a look at.

bug

**Describe the bug (REQUIRED)** I have a sprite that represents a playing card …that has 2 textures. One for the front and one for the back so that I can swap them in the fragment shader. Just adding a third sampler for a normal map, makes the game crash on running. **To Reproduce (REQUIRED)** Steps to reproduce the behavior: 1. Open game.project 2. Select Project>Fetch Libraries 3. Build and run ( you should see a card back) 4. Open assets/materials/card/card.material 5. Add a 3rd sampler to Samplers using "+" called normal_sampler with the same settings as the 2 other samplers 6. Open main/objects/card/card.go 7. Select "sprite" in the outline 8. Select "assets/atlases/AC_normal.atlas" [NB: it doesn't matter which atlas is chosen] for the normal_sampler 9. Build and run to observe the crash **Expected behavior (REQUIRED)** No crash **Defold version (REQUIRED):** 1.7.0 **Platforms (REQUIRED):** - Platforms: macOS - OS: Sonoma - Device: MacBook Pro 14" M1 **Minimal repro case project (OPTIONAL):** [Defold_multitexture_bug.zip](https://github.com/defold/defold/files/15091955/Defold_multitexture_bug.zip) **Logs (OPTIONAL):** INFO:DLIB: Log server started on port 50093 INFO:ENGINE: Target listening with name: orac-2.local - 10.0.0.13 - Darwin INFO:ENGINE: Engine service started on port 50094 INFO:GRAPHICS: Installed graphics device 'ADAPTER_FAMILY_OPENGL' INFO:ENGINE: Defold Engine 1.7.0 (bf4dc66) INFO:DLIB: Initialized Remotery (ws://127.0.0.1:17815/rmt) INFO:ENGINE: Loading data from: build/default INFO:ENGINE: Initialised sound device 'default' Assertion failed: (i < Size()), function operator[], file array.h, line 494.
