Multimatte - odd channel switching

V-Ray V-Ray for Nuke Issues
1

Hi,
I am noticing an odd isssue with vray 5.0 and nuke 13.0v5.

I have objectIds that are being used in multimattes, sometimes when re-opening the scene the multimattes switch so that the wrong ID/colours are being applied. It seems kind of random, and the object Ids themselves are not changing so there is no logical reason I can see for the multimatte to be rendering 3, 2, 1 (as an example) when it said to be 1, 2, 3. Has anyone else noticed such an issue?

Hey,

Sounds fishy, can you send us a simple scene representing the issue so that we can check what is going on?

Thanks!
