Hello,

in Mantra, it was straightforward to set up reflection and refraction visibility of objects. It was done at object level with refl/refr mask.

We now have to reproduce this functionality with Karma, but cannot find a way to achieve the desired result.

Example: Two refractive objects need only see themselves in refraction, never the other.

Any input and help is much appreciated.

Hi. Karma currently does not support category masks (or custom tracesets). Separate render passes may be the only workaround in this situation.

Thank you for the prompt response. We'll look into it.

Have a great day.
