Exit Portal Material doubt

[gmaisg]

Hi, I have a doubt. Lets say I have a render from inside a house (interior scene) and have some big glass windows, do I have to create a plane with a EXIT PORTAL material covering the hole of the window? What I want is to have the glass material (the effect) in the window but with the light coming from outside. Thanks in advance.

What you can do is create a plane behind your glass with the exit portal material and make sure it's normal is facing the camera. It should in theory let light in, but not out.

Also make sure your glass object has volume

Hi, thanks for the rapid reply. I will try it and was what I was thinking in doing.

If not extremely necessary, I'd suggest you not to have thick glass, to avoid longer render times.
For me Thin Glass does the job most of the times.

Ok, thanks for the advice. I will do that.

Well, that's great. Various setups, depending the speed that I will want in my renders, thanks for all of you, very usefull.
