Bumped into a issue when using the createDefaultEnvironment helper that I’m not able to resolve. Looks like there is a problem when using WebGPU and the groundMirrorFallOffDistance property of the helper. I get nothing rendered and this in the log:
BJS - [11:38:17]: WebGPU uncaptured error (1): [object GPUValidationError] - Error while parsing WGSL: :461:56 error: unresolved value 'vPositionW'
var reflectionDistanceFalloff: f32=1.0-saturate(length(vPositionW.xyz-uniforms.vBackgroundCenter)*uniforms.vReflectionControl.w);
^^^^^^^^^^
- While calling [Device "BabylonWebGPUDevice1"].CreateShaderModule([ShaderModuleDescriptor ""fragment""]).

Reproduction sandbox: Babylon.js Playground
The sandbox works when using WebGL, it’s just on WebGPU it crashes.
