Title: Help with caustics
Post by: Liberti0723 on 2015-11-16, 16:49:15

Hi, guys!
I need help with the caustic .I’ve never worked with it. I Read several forums, all solutions are there in my case do not work, probably I do not understand something. For water I use box with noize on bump and standart parameters in material. When I am using bidir all begins gradually black. And it's no matter which mode bidir I use the result is still terrible. I attached two images 1. Render engine: progressive 2. Render engine:Bidir/VCM
Please help me)

In Bidir/VCM try to change mode to VCM.

Try simplifying scene for the caustics. Only water all the rest midgray difuse material an light sorces that should produce caustics.
