https://bugs.freedesktop.org/show_bug.cgi?id=78951 --- Comment #6 from Marek Olšák --- The hw GS mode A should be able to do this, which is basically a VS which gets PrimitiveID on the input. -- You are receiving this mail because: You are the assignee for the bug. -- next part

https://bugs.freedesktop.org/show_bug.cgi?id=78951 --- Comment #1 from Michel D?nzer --- AFAICT the hardware doesn't provide any way to retrieve the primitive ID without a geometry shader, so we'd probably need to use a passthrough geometry shader for this. Any volunteers? -- You are receiving
