Animated and Static Irradiance in the same render.

[Lehm_2001]

I've been thinking more about moving objects. Played with brute force a bit, and determined its just too costly. Unless you have a big farm that is. Using an animated irradiance map is much quicker but still adds quite a bit of time. You can render out the moving objects and static geometry separately, but that requires like 3 passes to do correctly. Quite a bit of unnecessary overhead I think. It'd be great if instead you could specify 2 irradiance maps. A static one and an animated one. When a ray hits an object marked as movable it would use the animated one otherwise it would use the static one. If possible this would be a massive time/disk space saver and a simpler composite. You'd still have to go through the trouble of precalcing 2 irradiance maps...that is unless it were possible to calculate the static map while it was doing the animated one.
