Hi,

I'd like to render lighting effects for an indoor environment, where there are about 20 different light sources
You can roughly imagine it as a cinematographic set -- the subjects to be illuminated are mostly humans.

Currently, I simply model the light as a 9-values vector (by using a spherical harmonics representation).
Do you think it could be an appropriate model, or is it too poor?

If you want specular, then SH isn't really going to work. Good specular is very important for getting realistic-looking skin, so you may want to apply at least a few lights analytically.
