If I want to do a radiosity render of an inside envrionment- what's the best light source option ?
I've got a church interior with about 6 hanging lamps and I wanted to do a test to see what an accurate lighting model would look like.
I'm familiar with skydome setups, but how would I do a set up for an interior lit from within ?

Thanks !

Try using spotlights with both a large cone angle and falloff setting. Use Large shadowmaps with a low fuzziness setting. Then just apply radiosity as normal. I just did a large interior of a hanger type building and it worked our pretty well for me.

I found that doing the inside of a bar is too cpu intense if u use like 26 lights and radiosity.What im experimenting with his radiosity the room with no contents, Bake it then render with objects and their lights.

Im a nocie so some tutorials would be nice to help us.
Is baking the key?

Baking is the key for animation... If you don't want to re-render all the radiosity on every frame... You fake/bake it...

Up the intensity with radiosity and start of with lower quality settings to get an idea... When you get closer, increase the quality... Interpolation/threshold...

for faster render times, there's always innercaster ( a fake radiosity solution)

flying in the face of what we've always been told about ambient lighting, you actually need some of it to help LW radiosity engine along a little, especially for interior settings.

Here is a thread from a few days ago that might have some helpful info for you...look into using some HDRI lighting in combination with Low Radiosity settings and Motion blur...

My God that's the best tip I've seen in years! EVERYBODY should be doing it!

I got render times that were 5 times faster! That's dual 3ghz speed out of my dual 450!
