Hmm, doing this for some time, got tired of rendering 36 or more lights with shadows on (expecially soft ones) ! :)

I also add some gradient to the light rig as well....

I tought this was well known tehnique :)

Never combined it with HDRI sphere, but looks like a nice combo !!! :)

Thanks for the info, Drac :)

BTW, I liked your Wings tutorial, just got trough it the other day, it will be very useful in my modeling poligonal objects in C4D, cuz I do only nurbs for now (wings is more simple too) !!! :)
