[PyMOL] de-speculating?

[Thomas S. <ts...@ex...>]

 
Hi All --
 
Would anyone happen to have a "recipe" handy for turning down/off the
specularity (of CPK spheres especially)  in PyMOL?  I happen to be a fan
of more "matte" surfaces and find the highlights to be rather extreme.
I've been messing around with all of the parameters as found on
PyMOLwiki:
 
Spec direct
Spec direct power
spec power 
specular
specular intensity
 
as well as
reflect
ambient
 
et cetera
 
but haven't really found the sweet spot.
 
My current settings look like:
spec_count, 1
spec_direct, 0.0
spec_direct_power, 2000
spec_power, 2000
spec_reflect, 2
specular, 0
specular_intensity, 0.5
ambient, 0.08
reflect, 0.66

This is close, but loses some dimensionality in the CPK spheres (they
now look flat in the middle).  Oddly, the spheres look great in the GUI
(unrendered) but the ray-traced version seems to clip the shading/color
distribution badly....
 
Any suggestions?
 
Thanks!
