Is there a trick way of avoiding radiosity but still get a similar result. I know it is'nt going to be the same, but I've used translucency at times, and it works somewhat. I'm animating at home. Complex lighting/models/textures/bumps. Any suggestions?

A bit of occlusion gives a radiosity-like feel, same with soft shadows from area lights.

Stupid question, but how do I do that? Occlusion!

Careful placement of lights where radiosity bounces would come from.

OK, Thanks!

Light domes :)

Basically use my meshtolight plugin to arrange a whole bunch of shadowmapped lights in a dome around your object to give it that soft shaded look.

Sorry, that should be Lightmesh plugin :)

OK, but I have a room with all kinds of things like beam structures coming in from the ceiling and other architectural stuff. I'm not lighting a single object, its a room interior. I have lights set above the beams, and they cast shadows over the room walls and floor.

Spinning Light Trick (which I have to say, I've never tried!)

Buncha muncha cruncha area lights.

Mmmmmmm area lights.

There is also a 'gradient' trick, though I've only heard about it and seen the result. I don't know how it works.

Gerardo was responsible for that one I think, but I'm not positive. He used nulls to 'manually' create lighting gradients between walls. Quite difficult to set up for complex geometry though I'd imagine.

Yes Gerardo likes it complicated ;) I have used a more simple approach of only luminosity and ambient occlusion for one interior rendering project ( http://www.im-graphics.com/v-2006/2006-siemensb2.jpg ), works fine. But i guess raydiosity will be faster in the end with less setup time.
