Two depth buffer in a single pass ?

[jay19240]

Hello,
It is possible to have two depth buffers in a single pass ? I want a depth buffer with front-faces and another with back-faces.
Or in other words, first depth buffer with cw and second with ccw.

It isn't possible with depth buffers, there can only be a single one attached.

You could do something like use a depth buffer with depthwrite and depthCompare <= and a R32Float attachment with GPUBlendOperation max, but that's kind of a hack and might not work depending on what you want to do with the data afterwards.

Well, so my only non-tricky solution is to create another pipeline with just change primitive culling, right ?

And render all objects again in a new render pass yes.
