Hello, i am on vray 6.2 and 3dsmax 2025. i can’t see material ids in neither multimatte nor vraymtIID render element. Cryptomatte is not working for my use case. Thanks in advance!
Note that the mat ids here are the ID you set for the material itself (the 0-15 menu in the material editor) not the material id of the polygon in the model. Could that be the issue? You also have to check IsMatID in the multimatte settings.
