The utils.wgsl shader has an implicit dependency to another shader

[torsteingrindvik]

Bevy version

a3baf2a (very recent main)

What you did

I did #import bevy_pbr::utils in my own plugin's shader.
I want to use that for things such as PI, random1D, and coords_to_viewport_uv, which can be useful to anyone.

What went wrong

error: no definition in scope for identifier: 'normal_prepass_texture'
   ┌─ wgsl:44:37
   │
44 │     let normal_sample = textureLoad(normal_prepass_texture, vec2<i32>(frag_coord.xy), 0);
   │                                     ^^^^^^^^^^^^^^^^^^^^^^ unknown identifier

Additional information

theories about what might be going wrong

It's assumed that mesh_view_bindings.wgsl is imported.

That file defines normal_prepass_texture. But I can't just import that shader because it defines lots of bindings which I'm not using.

workarounds that you used

I can just copy-paste the stuff in utils.wgsl into my own shaders.

This is happening because utils.wgsl now needs mesh_view_bindings.wgsl, as of the prepass getting added to bevy. Perhaps we should move the prepass sample functions out of utils.

I really hope we can get the new shader import stuff soon which would make this a non-issue. For now, I'll just create a prepass_utils.wgsl
