Glass refraction and background image problem.

[visualform]

Hi!

I have probem rendering scene in 3ds Max with Corona. the problem is that i have plane with background image and glasses in the scene do not render it ( i have remove glass from the windows ) and it's the same with corona light material on the lamps with some texture  on the lamps on the lamps .  I'm attaching screens with glass material and etc.

Thanks in advance!

Flipped normals maybe ?

How did you make the background object? (what material does it have?)

[visualform]

Normals are ok, and here is material i used for plane.
I tried marking and unmarking those options "visible in... " all 4 of them.

I cannot reproduce it. Looks like it could be something that was fixed in newer versions. Can you try reproducing it in some simplified version (like my scene here)?

There's possible explanation to your problem: https://forum.corona-renderer.com/index.php/topic,4998.msg46285.html#msg46285

I used the link above and mark in glass material "thin ( no refraction) and in background material " emit light ". It's working now.

Thanks a lot to all of you!
