Old topic, so I didn't see it the first time around.
Allan, what a helpful tip!
Have you used the Modify Viewpoint? Using that, you only render the radiosity part once, then reposition the view and do the Raytrace section, so it only takes a few moments for all the following views. As long as you change the names of the file each time in between, then you can get as many image angles as you want without doing the Radiosity again.
I guess I knew this (I've read it before), but I've never really taken advantage of this option before. Thanks.
Robert,
really nice work.
