Photon map broke!

Not sure what happened, but for some reason I suddenly get no secondary light bounces at all when I use the Photon Map on a particular scene. Has this happened to anyone else? It was working fine before. I tried reinstalling, starting all my settings from scratch, etc. Might it have something to do with X-refs?

Here’s another weird thing: yesterday when I was working on this scene (an old project that I’m bringing up to date) when I converted one material, my main wall material, to a VRay material the calc phase would take forever and everything got all washed out.

:cry:

with the Photon map you can only use VRay Mat’ls, do you have any Standard Mat’l in your scene?

Sorry, I forgot about that. Man what a PITA that was. More than 200 materials I had to convert, most of which could not be converted with that utility.

Horror :twisted: good luck
