Updated VXGI branches (both 4.9 and 4.10).
- New build of VXGI with slightly improved performance (0.91 CL 20159377).
- New diffuse tracing options: “Refine Sparse Tracing” to fill holes in tracing results, and “Flip Opacity Directions” that changes how occlusion works - sometimes mode looks better.
- Added VxgiAnchor actor class to allow users explicitly control clip-map location - it’s in the Lights category. When there is no such actor or it is disabled, the clip-map is located in front of the camera, as before. The precedence of VxgiAnchor’s over each other is undefined, i.e. if multiple anchors are enabled, one of them will work, but there’s no guarantee which one. They can also be controlled from Blueprint.
