glass reflection (?) error

[skogskalle]

Hello,

why do I get this big blue circle in my glasswall? The glass is very standard, full reflection, full refraction, no fog, a slight gray diffuse instead of black. The pattern is a separate object, a plane with an opacitymap, placed about 0,1 mm outside the glass.

Using vray 3.50.03.

Thanks in advance!

ok, so placing the opacitymapped plane 2mm over the glass gets rid of the problem. In this case it works, since the building will be viewed from a distance, but it would be nice to know why the error happens when the objects are too close to each other.

Can't say for sure without looking at the scene. Can you share it to support@chaosgroup.com? Thanks.
