Sometimes when i render in yafray i get really strange results.
Like this one. Why is there a blue light? NOTHING is blue in my scene but the
background. I have 2 boxes that are complete closed. So no background-light
should come into my scene. And i have made sure that the glasses do not stick trough the plane.
Another thing is the crappy glass. It’s all distorted. Why?
Looks like you don’t have enough light. That blue is probably caused by the GI, it still may be picking it up from the world settings. I’m not expert though so I could be wrong.
