RE: [PyMOL] Colors and ray-tracing

[DeLano, W. <wa...@su...>]

My guess is that you may still be showing sticks in the original object, =
instead of just cartoons.  If you have the same overlapping =
representation in two objects, it isn't predictable which will show up =
in the ray-tracer, and you can get exactly this behavior, where you see =
one color in OpenGL and a different one in the raytracer.

Here is the general sequence of steps you'll want to follow to insure =
success:

load prot.pdb
create cpy,prot
hide
show cartoon,prot
show sticks,cpy
color red,prot
color green,cpy
ray
