Reflection Catcher adds black outline

Hi everyone,

I was glad to see that the reflection and shadow catcher work so well by now.

But, recently I tried to use it and as a result got a black outline around the bottom of suzanne and other objects. On top of that, there is some strange behavior when combining combinations of the shadow catcher / reflection catcher options:

Render with shadow catcher and reflection catcher enabled (no materials applied)Render with shadow catcher and reflection catcher enabled (no materials applied)

Fig. 6: Reflection catcher only (material applied to both suzanne and catcher plane)

This behavior is really strange and I tried to isolate and find out what might cause it but I have no clue. I also tried:

  • Switching between GPU and CPU hybrid, GPU only
  • Render border on and off
  • Changing bounces (standard, then full amount [50])
  • Looking at the reflection catcher pass (the outline kinda shows in there)
  • Reinstalling RPR

If this could be looked into, that'd be great, since this is not usable for production pipelines.

 

Thank you
