a few questions concerning background and reflect

Support Basics & Interface

hey everyone.

I dying here trying to figure out the following:

  1. I want to use an HDR image cast light tones onto my scene, but I do NOT want the image to show up as the background in the render. Can’t for the life of me figure it out.

  2. I want to use a map (a black and white image) and my UV coordinates to specify where the “ray mirror” in the mirror transp will make reflections. I feel like that should be easy like pie but can’t figure it out.

If anyone could help me with these things i would GREATLY appreciate it.
