I've used the vray blend material to do this before.

Bottom layer would be a vray light material with an image in it for the vague shapes/distribution behind the glass (light spread/colours) and the layer on top was the glass with masks in reflection/refraction to add the seams.

cubiclegangster: That sounds like a good method. Do you have an example that you can post? Thanks.

I cant remember what job I used it on unfortunatly. There were 2, one a lobby and a school but it's going to take me a while to dig for.

I'll browse whenever I do a test render today and post it up if I find it.

yes this sounds good, i'm going to do some tests with your methods.
would be nice to see the result you got

thanks

You can also try the VRay2SidedMtl. This works good for me. Refer to spot3d for more info.
