I have a building with sheer glass walls and have lost all transparency when rendered. What is behind the glass ar objects with VRay light materials that are color mapped. Primary light source is an hdri with one VRay spherical light as fill. I’ve tried the whole range of combinations of reflection and refraction from pure white to pure black but am getting only the very slightest hing of what’s behind the glass (at pure white refratction and bure black reflection). Shadow casting is off for the glass objects. I’ve done this many times before and am completely baffled. Could I have accidently hit some render parameter? or any other suggestions? Thanks. Harold
can we see an image?
How about the < Affect shadow > param in your glass materials ?

Also make sure “refractive Caustics” is ticked in the GI rollout of the render panel. Otherwise “affect Shadow” wont work.
In the end, it may have been a corrupt geometry issue. I 3ds’ed out, reimported, reassigned the same materials and all is working as it should. Thanks
