Maybe there is already a way, but I did not find it:
It would be great to enhance image-sampling based on objects. This might especially for Hipoly objects that would tend to produce heavy noise in animations.
We are just having the issue of Hipoly trees against a sky: the sky (and other simpler objects) does not need any extra sampling, but the trees need a minimum value of 3 and more, to catch the fine branches. It is a “waste” of rendertimes to crank up the sampling substantially just because of a few objects.
Same goes for cars that need fine sampling to catch fine seams …
If it is technically doable at all, I could imagine some spinner in the VrayProperties settings …
Best regards, Peter
P.S.: Of course we are happy for any hints in the current version as well!
