Reflection Pass Unusable

Has anyone encountered an issue with their reflection passes being strange colors and super noisy? The final RGB pass is totally fine. I’m using the standard brute force + light cache workflow. All my other passes are fine. Not sure what’s going on here.

Thanks,

I think I was told that everything now is in the specular pass.

I brought it up right after NEXT was released and I never really worked it out. You can search the forum and read the discussion.

Does your scene contain any standard material or other stuff that is not supported? Any objects without any materials at all?

Hmmm… Most of our geometry is imported from Revit. So, there are probably a ton of Revit materials or objects with no materials. I bet that’s what is causing the issue. Maybe I’ll just run a v-ray scene converter and see if that fixes it.

I’ve converted all of the materials and assigned materials to objects that didn’t have them, but I’m still getting the same result. I hid half the objects and the reflection pass rendered fine though. I can only assume that there is some kind of corrupted geometry from Revit in the file somewhere. We did have a lot of issues with crashes with this file, so that seems like the most likely explanation. Not a V-Ray issue.

Thanks for your suggestions, though!
