black spots in yafray reflections

black spots keep appearing in the reflections when i render with photon mapping any idea why?


It’s a known bug that will hopefully be solved in the next release of YafaRay.

One of the materials in your scene is triggering some mathematical error.

What might help is to:

  • avoid overly reflective materials or those with a ‘100% white’ diffuse color,
  • experiment with the Diff. Radius.
