depth prepass stuff not being imported

[bananaturtlesandwich]

hi just trying to see if i can get some materials which use depth prepass working and looked at the example for reference
my Camera3d has the DepthPrepass component and this is my shader code

#import bevy_pbr::mesh_types
#import bevy_pbr::mesh_view_bindings
#import bevy_pbr::prepass_utils

@fragment
fn fragment(
    @builtin(position) frag_coord: vec4<f32>,
    @builtin(sample_index) sample_index: u32,
    #import bevy_pbr::mesh_vertex_output
) -> @location(0) vec4<f32> {
    let depth = prepass_depth(frag_coord, sample_index);
    return vec4(depth, depth, depth, 1.0);
}

but i'm getting this

2024-06-02T17:26:27.944953Z ERROR bevy_render::render_resource::pipeline_cache: failed to process shader:
error: no definition in scope for identifier: 'prepass_depth'

   │                 ^^^^^^^^^^^^^ unknown identifier
   │
   = no definition in scope for identifier: 'prepass_depth'

any ideas on what i might be doing wrong?

Can you share a minimal reproduction. The prepass_depth function is only gated on the prepass being enabled, but you said you already added the DepthPrepass component to your camera so something else is missing but it's hard to know without more code.

The only thing I can think of is that you used the example from main but are using bevy 0.13 as a dependency, but IIRC that code hasn't really changed on main so it shouldn't be the issue.

yeah definitely not the issue since the only 2 commits since 0.13.2 just changed the text size

[bananaturtlesandwich]

guess i'll make an issue

If you look in ssr.wgsl, there is prepass_utils imported from bevy_pbr like in your example, and in other place prepass_utils::prepass_depth is used instead of just prepass_depth in your example. Can you try import bevy_pbr::prepass_utils::prepass_depth or use prepass_utils::prepass_depth?
