How to write to depth buffer

[CodedNil]

I've been working on converting my shaders from wgsl to rust-gpu, it's all perfect except I got depth compiling with this. The issue is that it simply isn't writing to the depth when I preview that on bevy, the pipeline on the bevy side is identical to what I had with wgsl before.

#[spirv(fragment(depth_replacing))]
fn main_fs(
#[spirv(location = 0)] uv: Vec2,
#[spirv(uniform, descriptor_set = 0, binding = 0)] view: &ViewUniform,
#[spirv(descriptor_set = 0, binding = 2)] base_texture: &Image!(3D, type=f32, sampled=true),
#[spirv(descriptor_set = 0, binding = 3)] details_texture: &Image!(3D, type=f32, sampled=true),
#[spirv(descriptor_set = 0, binding = 4)] weather_texture: &Image!(2D, type=f32, sampled=true),
#[spirv(descriptor_set = 0, binding = 1)] sampler: &Sampler,
#[spirv(location = 0)] out_color: &mut Vec4,
#[spirv(location = 1)] out_motion: &mut Vec4,
#[spirv(frag_depth)] out_frag_depth: &mut f32,
) {

This is the wgsl I had before:

struct FragmentOutput {
@location(0) color: vec4,
@location(1) motion: vec4,
@Builtin(frag_depth) frag_depth: f32,
};

@Fragment
fn main(in: FullscreenVertexOutput) -> FragmentOutput {
