Reflected and Refracted Channels

[akinlolu olugboji]

Whenever I assign an  images to these channels the rendering background blackens out, even though both channels are assigned with the same images. This can be corrected in post processing but why.

 

The whole idea is to have the sky (which is the image assigned to these channels) to reflect in the windows.

 

Added the *.nxt if that will help.

I haven't tried this for a while, but it should work, particularly with the packet tracer.  (The Path Tracer has a lot of limitations re: color backgrounds.)  Hard to say if your reflective channel is working, but I definitely wouldn't mess with the refractive channel in a drawing which uses RPCs.  Set it back to Visible.  If it's even slightly different the background you see through the RPCs will be different and you'll be able to see the outline of the cutout.  If you think there's a problem, provide a simple example (without RPCs but with some refractive and reflective materials for me.)

Staying away from the refracted channel sure did the trick.
