   Dummy buffers, zero values.
  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.   
  Which API are you using?   ;Which API are you using?I'm working with Direct3D11 and its full feature level.
