MatID element rendering crunchy

[insleight]

Edges of my MatID render element is rendering quite crunchy. Looks like it is not anti-aliased.
Vray version 1.50.sp3a

Any ideas?

Use the multimatte render element.

Yes, I like multimatte element very much too.
You can add several multimatte elements at the same time.
Mat id 1,2,3 for one multimatte element and mat id 4,5,6 for another and object id 1,2,3 for the third multimatte element and .......
And it's very useful when you composite or edit with AE or PS or others.
