Speckles on multimatte elements

[tricky]

Anyone had this problem where the rgb multimatte elements are speckly? Doesn't seem to be coplanar and there is no geometry hidden from camera. The rgb beauty pass renders fine.

I am using object IDs to generate the multimatte elements.

Mmmm. About to upload an example, but it shows no speckles!!! Am I going mad or dows the max frame buffer show speckles in multimattes, but the saved images do not????

[instinct]

what kind of speckles ? all around or only in specific places ? mind you that MMRE obviously uses the sampling of the RGB so if there is very little sampling (little contrast or dark areas) then the MMREs are samples as low. And while it maybe invisible in the RGB it can be very visible in the Mattes.

I had this too, saving the file usually gets rid of them

If it goes away on save might be one of the display settings in the VFB ? Does it also show in the max vfb ?
