Title: Glass material & background
Post by: nicolasZ on 2016-06-29, 16:41:03

Hi guys,

I have a problem with glass material :

I have a projet with a background ( plane with light material + bitmap) and if I disable thin in my glass material, there is a problem, my background become white ...
And if I enable thin, my background is ok, but I lose the refraction effect in my glass.

My project is lighting with a corona sun an there is a corona sky in the environement slot // Changing IOR refraction change nothing.

I don't know how to deal with that, if anyone can help me, it will be great !!

Hi, you should either use light mtl with emit light off, or rayswitch - see: https://coronarenderer.freshdesk.com/support/solutions/articles/5000515605
Let me know if you still have some problems when using these methods.

But I hope you did disable GI using the shadowcatcher material? Otherwise the render times/noise could be horrible.
