Chamfer for glass - gives fireflies, nothing can remove them. Even a total shutdown visibility of the sun! It's a bug!Only tomorrow I can get a good result ((.
Have you tried to use (or change) AA filter? Some time it helps to remove these dots...
2 iliyang: PT + PT can not cope with this task in a reasonable time!Bidir - give similar results with the VCR, but will not be seen underwater caustics.The purpose of this test - solve the complex task in the exterior to understand the capabilities of the algorithm. At the moment, none of the popular renderer is not able to!
The point I was trying to make is to compare the quality achieved by PT, BPT and VCM in the same time (say 3 hours). I understand very well that neither PT nor BPT will be able to produce an acceptable image, but that's the point of the test. I'll be giving a talk about VCM at Siggraph in a month, and if we can get this comparison on an awesome scene that highlights the strengths of VCM, I can show the images in my talk, which will give Corona some publicity.
Okay, I'll do it :)
