Houdini and V-Ray - setting up Cryptomatte for instancing

Here's a way to set up Cryptomatte in V-Ray for Houdini for efficient control with instancing.
Edit: One thing I got wrong was the name/path attribute class - points is better, vrscene size baloons with prim :)

Hey, The tut was very useful. Can we use the same method for mantra render as well.

[@HristoVelev]

It's a bit different in how you set up the AOV but otherwise yes :)

[@MrAvoronov]

This CPU or GPU render?

[@HristoVelev]

Alexey Voronov CPU but the same applies for VRAY GPU

@@MrAvoronov sorry seems like I don't have the scene for this one. Try rebuilding from the video, and it's a part of a bigger course I'm planning to do on VFH
