I rendered a scene from 3drender.com for one of my classes midterms.. when i render glass that is in front of or behind another glass bottle it will render black. So pretty much any over lapping glass will render black..how do i fix this and what is causing the problem?
Depends on any number of things. What material library is this material from? Is it an arch viz mat, mental ray mat, etc? Refraction settings in the material itself play a big role in how they render. Finally, you need to have high raytrace settings, as well as modified FG/GI/Caustic settings for glass to render properly.…
