Render a pass that doesn't write to the color bufffer. Use clip/discard as you please.
Render another pass that writes to the color and not depth buffer.
Frage
Is it somehow possible to control for each fragment whether or not depth shall be written to the depth buffer?
I want my object to be depth tested properly (therefore I need to output accurate depth per fragment for testing), but I want only some of the fragments to write to the buffer.
Any way to do that?
