Yo @Deltakosh or @sebavan … Is there some kind of WEBGPU compatibility mode or something like that for WEBGPU on the playground that i am missing when trying to use in a boiler plate template ? I can load the samplescene.gltf and playerarmeture.gltf just fine on the playground in webgpu: > **[Babylon.js Playground](https://playground.babylonjs.com/index.html?webgpu&BabylonToolkit#TWDYSM)** > > Babylon.js playground is a live editor for Babylon.js WebGL and WebGPU 3D scenes But when i create a app from scratch or use the vite boilerplate template (or any react project) I get this: ![Screenshot 2025-06-09 at 6.56.53 AM](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/8/0/8078093901bec81cff6e7fbbc63614919054ed63.jpeg) Note: WebGL2 runs fine. Its just webgpu in a project outside of the playground ---

Looks like your code use too many varyings ☹ limited to 16 at the moment ---

Yo are da man @sebavan … its actually called `setMaximumLimits=true` on the WebGPU options ---

I got another one for @sebavan For some reason on ES6, after 8.0 (may \> 7.50) my same model that works fine UMD and did before, now kinda SQUASHES down [https://www.babylontoolkit.com/videos/squashedavatar.mp4](https://www.babylontoolkit.com/videos/squashedavatar.mp4) ---

I have no idea what it could be 😑 @bghgary any clue ? ---

It looks like meshes are the same size, but connection points are offset vertically during movement. Maybe something to do with bone or animation definitions? ---

Hmm, I don’t see how UMD and ES6 can change the size of a model. ---

Me neither… But the UMD version, loaded here on the playground works just fine: > **[Babylon.js Playground](https://playground.babylonjs.com/index.html?webgpu&BabylonToolkit#TWDYSM)** > > Babylon.js playground is a live editor for Babylon.js WebGL and WebGPU 3D scenes ---

Yo @bghgary and @sebavan @Deltakosh I made two repos…One UMD and one ESM… same App.tsx and Viewer.tsx (excluding the imports) > **[GitHub - MackeyK24/UMD-StarterAssets: React Starter Assets (UMD)](https://github.com/MackeyK24/UMD-StarterAssets)** > > React Starter Assets (UMD) > **[GitHub - MackeyK24/ES6-StarterAssets: React Starter Assets (ES6)](https://github.com/MackeyK24/ES6-StarterAssets)** > > React Starter Assets (ES6) The ESM version squashes when you run (hold shift to run) and land from a jump Check you please check them out, see what you can find: ```auto npm install npm run dev ``` Thank you so much 🙂 ---

Can you try to simplify the code ? This is way too much to troubleshoot efficiently. Can you repro without the unity plugin and only the main character ? ---

Im afraid not, its a unity exported player model. Its really weird, that ES version is all squashed and the UMD is fine. Is same code for both. @bghgary … Just checking, have you made any skeleton type changes in the GLTF parsing since V8 ? ---
