Bug 261890 – [WebGPU] fragmentWriteGBuffers.wgsl does not compile

• Status: RESOLVED
• Resolution: FIXED
• Component: WebGPU

[Mike Wyrzykowski]

fragmentWriteGBuffers.wgsl from https://webgpu.github.io/webgpu-samples/samples/deferredRendering#fragmentWriteGBuffers.wgsl does not compile because it writes to multiple render targets and the locations are not specified.

I.e., in the generated output:

struct type0 {
    vec<float, 4> normal ;
    vec<float, 4> albedo ;
};

should be:

struct type0 {
    vec<float, 4> normal [[color(0)]];
    vec<float, 4> albedo [[color(1)]];
};
