Hide object from Refraction/Reflection

[saikkonen]

Hi, this might be an easy thing to fix but I had no luck so far....

I have an animation of a rotating house and have problems with the balcony's refraction. A cylinder with a texture is used to give the windows reflection but I want the balcony glass to be semi-transparent with white.

The cylinder that is used for reflections should only be seen by the windows.

What options do I have?

I think the screenshots explains the problem better.

Use the Vray refraction override in the Environment panel of the render setup. Just plug whatever texture you have as your background there.

There's something else that's weird with your balcony material, though. The window and wall look inflated when seen through the balcony glass. Does your glass object have volume?

I tried that but the reflection is not coming from the environment but from a plane on the other side of the object.

Camera <- Glass(only refraction) <- Plane with texture <- Environment

Maybe there is a way to exclude the plane from the balcony glass.

edit: No volume on glass...

yes this is problem in mental ray too, but in 1.5 vray there wasnt this bug , i found something what mask do , it called rendermask and its free to download and you can get rid of that refracton from image ....
