Can your rig handle a full cast shot? Get all of them in one scene together sort of thing?
I've thought about how I might do that. Straight up render them all together in one shot? Pretty sure not, but I might be able to do each one individually with low-res versions of the others in the shot to cast shadows and ambient light but not actually render them in the shot. Do that with each character, then put them all together in one image. So.... that's why I haven't attempted it yet. 8-/
I'm glad I stumbled upon your stuff! You do some great work!!!
