Hello everyone,

I must have missed something but why isn't there a depthAttachmentPixelFormat to the new Metal 4 MTL4RenderPipelineDescriptor, unlike the old MTLRenderPipelineDescriptor?

So how do you set the depth pixel format?

Thanks in advance!

Hello,

For color attachments first create an unspecialized MTLRenderPipelineState and then compile a new specialized MTLRenderPipelineState with a specialized color attachment configuration:

// ... Set specialized values

// Create new specialized pipeline
id<MTLRenderPipelineState> specializedPipeline = 
[compiler newRenderPipelineStateBySpecializationWithDescriptor:pipelineDescriptor
pipeline: unspecializedPipeline
error: &error];

You no longer need to set the depth format ahead of time; you can just supply a depth texture when setting up your render pass later on.

Oh, I see! Thanks, noah-w! That's a nice change... But why not do the same thing with colorAttachments?
