[PyMOL] movie and fog

[Alexandra D. <de...@ma...>]

Dear all:

I would like to make a simple movie of a structure ( a full rotation  
about the y axis) with a very strong fog effect. I have tried playing  
with depth_cue, ray_trace_fog settings as shown below  but I do not get  
as strong a fog effect as I would like. Adjusting the clip planes   
works nicely in the viewer window before the ray-tracing is executed,  
but when the movie images are written  out, Pymol seems to ignore the  
clip commands (?!).

# don't use "fullscreen on" instead use viewport command later one in  
the script
full_screen on
clip near, 20
clip slab, 50
clip near, 30
set orthoscopic=0
set antialias=1
set spec_power=200
set depth_cue, 1
set ray_trace_fog = 1

Any suggestions?

Thank you very much in advance,
Alexandra
