Hi everyone,

Reviving this thread. There are two methods to get a material select already and I was wondering if any of those is suitable for you.
One way is to use Light Path Expressions, basically a beauty (C.*) with a material label. For example if the material label is "myMaterial', the expression C.'mmyMaterial'.* would give you a material select for the material(s) with that label. Note that m is pre-pended to the label name in the expression.
You can read more about LPEs here: https://docs.chaosgroup.com/display/...th+Expressions

Another method is to use Cryptomatte in "Material name" mode and just mask out the beauty for any material.
Also, in V-Ray 5.1 the Cryptomatte now works with progressive sampling.

Would either of this work for you? It essentially produces the same result as the Material Select.
