There is a new build of V-Ray for Rhino now available that has a few small fixes. The Z-Depth channel was not working correctly with SR 1.5, so that was resolved. Also, there was an issue with saved GI solutions causing a crash when using distributed rendering, so that was also fixed. This is a pretty minor build, so there shouldn’t be any incompatibility between materials/visopts/scenes made with 1.05.04 (the "original: SR 1.5) and 1.05.29, the build that is now available. This time it really will be the last release until the next full version of VfR.
Nope…We were working on implementing some of the RDK stuff, but it wasn’t ready and would have required hardlinking to RDK…two reasons why it was taken out…next version it will be in there.
