Wasn’t able to complete the challenge so I rendered the wip in eevee. [![](https://img.youtube.com/vi/E2rdWeSmGBU/maxresdefault.jpg "LittleCoaster (wip)") ](https://www.youtube.com/watch?v=E2rdWeSmGBU) Unfortunately I can no longer build my older pbr projects so I tried out the current defold pbr core extension and the normal map textures are not rendering so I created an [issue](https://github.com/defold/defold-pbr/issues/16) and hopefully can finish the project sometime in the future. I created the scene with a “tiny world with big imagination” in mind, I wanted to simply add a button to have the camera ride the roller coaster and ferris wheel. 🎢 ---

Ah sorry, I’ll make sure it works. I’d like to see this as a sample 🙂 ---

Also, don’t stress about the deadline too much, if this is an issue, there is a grace period to submit 😉 We will start judging the entries somewhere closer to the end of this week most probably 😃 ---

I’m little late. It was a crazy day, sorry… Since the Tiny Worlds Community Challenge is a visually focused, this was not developed with optimization/performance in mind. You shouldn’t expect it to run everywhere. It may not work on mobile, not because of the logic/scripts, but due to post-processing effects that are not optimized. Repo: [GitHub - selimanac/defold-tiny-city · GitHub](https://github.com/selimanac/defold-tiny-city) Test it: [defold-tiny-city 1.0](https://selimanac.github.io/defold-tiny-city/) I also wanted to implement a day and night cycle, but I spent a lot of time on the graph editor (WIP) and the [DoF effect](https://forum.defold.com/t/depth-of-field-dof/81995). I would also like to thank @Piro for his effort and time in building the initial map. I didn’t end up using it, but I used some of his ideas. 🙏 Since this is a kind of practice for worldbuilding, I would like to share my thoughts on the current state of the Defold Editor while building this simple world. - Need persistent show/hide states for Outline. When the editor is closed and reopened, everything becomes visible again. - Project based settings for Toggle Component Guides, Grid, and similar options should be saved and reloaded. - We really need top, left, and right views to switch quickly between them. It is extremely time consuming to place 3D objects while constantly rotating the camera: [Front Top Left viewport presets in editor · Issue #8147 · defold/defold · GitHub](https://github.com/defold/defold/issues/8147) - Snap to grid, snap to grid, snap to grid(I know it is easier said than done). This was one of the earliest issues ([Manual grid size and Snapping are not working [DEFEDIT-1283] · Issue #1477 · defold/editor2-issues · GitHub](https://github.com/defold/editor2-issues/issues/1477)) of mine. - 3D particle system. - Move amount. We currently have only two options, Move Whole Pixel or Any. It would be nice to configure a custom step, like 0.1 or 1.5. I think there was a pull request for this. - More natural editor scene camera controls. Other stuff: - Also hit this: [Editor viewport transforms & gizmos completely broken if 180° rotations are involved · Issue #9410 · defold/defold · GitHub](https://github.com/defold/defold/issues/9410) - Yes please: [Add support for model LODs · Issue #7398 · defold/defold · GitHub](https://github.com/defold/defold/issues/7398) and also occlusion culling will be super - This is still an issue when particles are rotated: [True Billboards for 3D (label, sprite, particles components) · Issue #6820 · defold/defold · GitHub](https://github.com/defold/defold/issues/6820) - Yes please: [Add “fly camera” WASD controls in 3D Scene view · Issue #11185 · defold/defold · GitHub](https://github.com/defold/defold/issues/11185) - I’m not sure why this happens yet, but if I compress the cubemap textures using BasisU, they don’t render correctly on Chrome and Safari. It works fine on Firefox and desktop. Issue: [Cubemap textures render incorrectly when texture compression is applied · Issue #11566 · defold/defold · GitHub](https://github.com/defold/defold/issues/11566) - I couldn’t get webgpu to work. It just crashes in browsers. Issue: [WebGPU crash when Mipmaps is enabled · Issue #11567 · defold/defold · GitHub](https://github.com/defold/defold/issues/11567) ---

Fashionably late as they say. Congrats to the submissions very cool works! [![](https://i.ytimg.com/vi/q9JaMyFOEzw/hqdefault.jpg "littlecoaster: tiny worlds") ](https://www.youtube.com/watch?v=q9JaMyFOEzw) Turns out I made a big dummy mistake and had forgotten to export tangents with my models making the normals all wonky. I got it all working and added the project to github. > **[GitHub - FlexYourBrain/sample\_littlecoaster: Submission from the defold community challenge -...](https://github.com/FlexYourBrain/sample_littlecoaster)** > > Submission from the defold community challenge - Tiny Worlds I did also convert the pbr material/shader to work with skinned models in local vertex space but came across used up texture slots, so I used world vertex space for the animations instead. `ERROR:GAMESYS: Unable to bind bone matrix cache texture for component '/cart', no free texture slot available.` Thanks to @Pawel for putting these together, great exercises! cheers~ ---

Good stuff. I have found that after a few minutes of looking through files, the editor hangs with this project (release 1.11.2) and Beta (1.12.0); in addition they print out lots of `java.lang.NullPointerException` messages. Prior to hanging the games builds runs well. Linux 4GHz x8, using ~8GB (plenty left). Is this expected behavior for this project? Edit: I think the issue is pbr writing to /tmp a lot issue, which is not the fault of this project. ---

Thats not good, no this is not expected. Maybe some of these errors are useful to report? I did find in the extension readme - known issues : `There are several known issues on linux platform(s) currently, so we can't guarantee any support on linux currently.` ---
