Multi-pass problem

[lukas8410]

Hey Guys,

so I've got a problem. Let's say that we have a simple scene, where there is a glass wall in front a camera,
and some objects behind this glass wall further from the camera.

Now I need to render out Object buffers (render layer mask), for those objects, and I need this glass wall
to be present in the scene because of the refraction, which distorts the view of objects behind it.

The problem is that Octane multi pass system seems to "see" glass wall as a solid non transparent object,
which prevents it to render object IDs of the objects behind it.

My question is simple: Is there something that could let me render out those buffers without turning off
glass wall.

Cheers

P.S. I'm sorry but I cannot give You a scene file for this situation, but I do hope that I've exlained everything clearly enough.
