Render a matte of an objects reflection

[chrislavelle]

Hi all, I have an object held by a rigged hand. It is near a mirror. I'm using cryptomatte for the object node names.
So whilst i can isolate the object and change its colour. The reflection of the object is still the original colour. Is anyone aware if i can also get a matte of the objects reflection to change that also.
I have a workaround but if there is a facility to do this that would be great.

Best wishes and thanks in advance

Hi,
yes, it cannot work with Cryptomatte.

You need to use a Custom AOV:

+ Capture AOV:
