Thanks for the comments Cliff. You're right, the gothic image doesn't really show what kind of things can be produced - it's also a bit too dark to see what's going on! I'll try to create some other examples over the next few days and then post some screenshots (or links to them). I did try to post a response to my earlier thread on improving room renders (in this forum and the technical forum), but the browser munched it and I didn't feel up to typing it all in again at the time! Thanks again, Max
