Multimatte not working on VrayLightMtl & VrayCarpaintMtl

[fraggle]

Hello,
Is there an incompatibility regarding this 2 material and the MultiMatte render element?
I can't get it works, it render black instead of red/blue/green.
Mat ID have been apply on the material side and MatID is check in the MultiMatte render element.

Thanks

Heya

Silly question but u did specify mateID number right ? 1/2/3 and same on multimatte? Everything should work as far as I tested last night.

Thanks,
yes I triple check.
Using 3.x, could be a bug.

Interesting. Could you try new scene fresh settings maybe?

Hi Fraggle and Dedal,

Merry Christmas!

Actually yes, CarpaintMtl doesn't work with the Multimatte material ID's in the latest beta. I will add this bug in our system.
Thank you for the report. In the meantime you could use the Object ID option instead.

About the LightMtl, would it be possible to send us a scene. In my tests everything works fine, but may be there is a setup where it doesn't.

These are fixed already for the next build. Thanks for the report!

Best regards,
Vlado

Thank you for the scene.
If you update to the latest (latest Beta 3.05.04) build, this scene setup with Light Mtl and Multimatte should work fine.
