View Full Version : Need reminder on radiosity pass with black background

How do I render a radiosity pass without the background showing up? In other words, I need a black background in the rendered image, and I can't remember how to exclude the backgorund but still get the radiosity light and reflections from the background to show up on the object being rendered.

Just use a black (or whatever colour) image as the backdrop in compositing tab.

you can also put a black image in the background. That hides the other background environments like the textured environment plugin.
