Glass reflection
I have a glass column (using the default glass4 material)which is reflecting the background perfectly. I want to have this reflection but I actually need to change the background. So how can I retain this relection and change the background? I was going to add the texture to the reflection channel of the material, but I don’t see the option available. Any suggestions?
Thank,

What is your background? Real geometry, background object, sky object?

My background is an extruded circle with no caps and an image which is black with blue squares. So you are actually inside of this round room. My camera circles around the scene and this is the only way I knew to do an enviroment without corners. NEWBIE.
Does that help?

You can take the image on the extruded circle and put it into the Reflection or Environment channel of the column’s glass4 material

Yep, there are several ways to do this. As Brian said, you can put the image in your material’s environment channel and disable reflection. That will give you a different background from the image seemingly reflected on the object.
Another way to do it is to use compositing tags with the “seen by camera” and “seen by reflection” parameters. That way you can have two or more background objects and use them for different purposes. This is more flexible approach than using the environment channel.
