Is there any way to guarantee zero values in a vertex register without using an all zero dummy buffer of appropriate size?
I need zero values for some dynamic branching when no buffer is present. I realize I could static branch or provide a shader permutation in what I'm trying to do but the question still remains.
I'm thinking doing something like sending in a buffer with stride zero would act fine as a dummy buffer if whats in the registers doesn't matter, but what about when it does.
