Chris, Multiple light sources will be in the next release -- the code is currently in CVS. For future reference:
set light_count, 4 and modify the light, light2, and light3 vectors (if necessary) light0 is fixed along Z and has no default specular component. The Z axis light intensity is controlled via the "direct" setting. The "reflect" setting controls the aggregate intensity of the movable light (now lights). Cheers, Warren -- Warren L.
