NVIDIA GameWorks Integration

It would be great when GI someday replaces reflection captures altogether, but for the near term I think we need to keep options open for combining VXGI will all the tricks we’ve come to know and love. I think that reflection captures can produce finer resolution reflections than VXGI will be capable of doing on current hardware. That is, VXGI produces reasonable diffuse reflections and decent specular highlights, but if you are looking for a mirror effect, with VXGI you would have to crank up the number of voxels, increasing the cone tracing load dramatically, etc. I might be misinformed on that, but I think that’s the case. So I would look to VXGI to replace reflection captures in many circumstances, but not necessarily for mirror-like surfaces.
