All MultiMattes have small dots in render

[Okke]

Hi,

We encountered a strange artifact in our mulitmatte renders. All material ID's in multimattes are rendered with small dots. The other renderelements all look fine. We have tested by placing new objects into the scene but all objects with material ID's have the same issues. So it looks like the problem is in the scene and not in the object or shaders.

Anyone familiar with this problem?

I've attached a screenshot of the issue.

Hello,

What version of V-Ray and Maya are you using and is it possible to upload a scene, where the issue is reproducible?

Thank you,

We are using Maya 2014 and Vray build 2.40.01.
I need to try if the issue is reproducible as I can't upload my scenes because of a NDA.

For now we've fixed the issue by resetting the render settings. So it seems to be in the settings, but we couldn't find any difference in settings compared with scene which render perfect.

Try to export a Vrscene file from each setup and then compare them to see where are the differences.
