I'm having trouble selecting which instance (of a draw call) and which vertex I would like to debug as I'm stepping trough a vertex shader in the visual studio graphics analyzer (2015). I am able to select by pixel which particular draw call I want to step trough a shader for, but it seems that...

Ok, thanks. Shame it's not accessible on PC. Just to be clear -- I was not envisioning specifying this type of vertex decomposition in the shader, in a fully programmable way. For me it would be enough if I could specify the decomposition completely on the CPU side, as context for draw calls.

Suppose I have some vertex position data, where several vertices have the exact same (x,y) coordinates, but in general have different z coordinates. It would then be natural to decompose the vertex storage by indexing into two vertex buffers: one for the (x,y) coordinates, and one for the z...
