Thanx for the suggestion. Alain.
I am using the "normals on" and "media on" switchs. All three types of
media, emitting, absorbing, and scattering are finding their way into this.
I hadn't thought of using such huge intensity on lights as you suggest, but
I am coming to the conclusion that that's what it will take. A LOT of very
bright lights that fade very fast.
