View Full Version : Rendering in darkness?

I've got a scene (hopefully going to animation) that is rendered by a single light source, which has linear falloff. There is no radiosity. I was wondering if anyone knew whether or not the engine renders things that aren't illuminated, objects that have no light touching them whatsoever. It'd be a pain to try and toggle the visibility track for every object the light may or may not be illuminating so I'm hoping it doesn't. Anyone know?

Try and experiment,do a render the way the scene is now and note the time,then put tags on the non lit objects that omit them from camera and note the time again :)

even an object in pure darkness will be rendered, just faster.

for emample put a sphere in a scene with no lights and no autolight, and render it, note how long it takes, now place it in an HN object with a setting of say 8 and rerender it shoudl take slightly longer
