webgpu: 3d_scene example panics when pbr_pcss feature is enabled #16000
Description
Bevy version
main
bisected to #13497
Relevant system information
AdapterInfo { name: "", vendor: 0, device: 0, device_type: Other, driver: "", driver_info: "", backend: BrowserWebGpu }
Chrome Version 129.0.6668.101 (Official Build) (arm64)
(macos / m1 max)
This does not seem to be platform-specific. I also tested on:
win11 / nvidia 4080
Chrome 129
What you did
cargo run -p build-wasm-example -- --api webgpu 3d_scene --features=pbr_pcss
