Nat,

ray_shadows is a global setting (only) -- changing it for individual objects has no effect.

set ray_shadows, 0
ray

will work.

Cheers,
Warren

Subject: [PyMOL] mixing ray_shadows states


I'm trying to make a high-quality figure showing ligand binding in a
cleft, incorporating sticks, electron density, and some combination of
cartoon/surface/lines for the protein.  Ray-traced shadows make the
perspective much clearer but also add visual "noise" - for instance, the
electron density casts mesh-shaped shadows everywhere.  Is there a way to
prevent specific objects from casting shadows?  I tried

set ray_shadows = 0, mesh1

but this doesn't seem to have any effect.  (This is with a very recent
beta.)  Is it even possible in theory for the raytracer to support such an
option?
