Marc Posted November 21, 2007 Share Posted November 21, 2007 Has anyone seen this message before : mantra: Aborting photon generation due to an extremely low photon storage ratio. Try using a more accurate photon target. I've tried everything from moving my light closer to scaling down the scene to increasing the amount of photons. Still get the same message. I'm trying to do caustics. Cheers Marc P.S. houdini 9.0.725 Quote Link to comment Share on other sites More sharing options...

photex Posted November 26, 2007 Share Posted November 26, 2007 I guess I'm forging new ground then? Sallying forth into the great unknown? M I guess so! But I'm interested to hear more about this if you do figure it out. Does using a different build affect the issue? Quote Link to comment Share on other sites More sharing options...
Jason Posted November 26, 2007 Share Posted November 26, 2007 Hey, I think this is happening because your PBR > Glossy Limit might be set to 1, meaning that there are no extra glossy bounces to cause caustics. Try boost the Glossy Limit? Quote Link to comment Share on other sites More sharing options...
Marc Posted November 26, 2007 Author Share Posted November 26, 2007 Good thinking! But no, that's not it either . At least, I set the Glossy Limit to 5 and I still get that error. Unless 5 is still too low? I'll play a little more this morning. thanks Marc Quote Link to comment Share on other sites More sharing options...
