RE: [PyMOL] Light source questions

[Warren D. <wa...@de...>]

Chris,

Multiple light sources will be in the next release -- the code is
currently in CVS.  For future reference:

set light_count, 4=20

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
