GPU : "Material select" render element

is there an ETA on when the Material Select render element will be available for gpu?

There isn’t, however, work for the element’s support is in progress.

ok thanks for reply.

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.

yeah i just had a quick go of the cryptomatte masking yesterday…v cool thx mate :slight_smile:
