View Full Version : Blackhole and cast reflections

Is there a quickway to make a object cast reflections and be a blackhole at the same time. I want to make a seperate reflection pass for a window that's reflecting other objects and these objects need to cutout the window as a blackhole. Right now I turn the primary visibility off for all the objects that needs to be visible in the reflection, and then I duplicate all the objects and give them a blackhole shader. It's not really a flexible way and I get flickering with final gather so I hope there is a easier way.
Thanks, Robbert

I suppose you need use background material

That's only for the object that reflects the other objects (the window in this case), I use mip_matteshadow for that. What I mean is how can I let the other objects reflect in the window, but also that the other objects cut out the window as a blackhole at the same time.

just create a mask as alpha for the object then use that alpha in compositing
