AO is a good option and I’ve had some success with that.
Radiosity I find is a bit of a hassle, especially on complex scenes.
I’ve tried the BRayBaker script, but never got it to work. There were always faces that would vanish after the script had run. Maybe I’ll have another crack at it.
Really? I didn’t know that. Yafray is usually faster than Blender internal in my renders. We’re talking of approximately the same image quality, right?
I’m suprised you find Yafray faster. Maybe on a very basic scene they’d render in a similar amount of time. But for more complex scenes I find that the samples, and shadow quality have to be incresed to prevent the ‘staining’ that is produced. i.e. in the corners of objects, and where objects are furthest away from the light sources.
Maybe you have some tips on how to keep render times down?
