[Chimera-users] POV-ray ignoring surface clipping

[Elaine Meng]

Hi Monica,
Sorry, it is a current limitation of raytracing from Chimera, as  
noted in the documentation:

<http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/raytracing.html>

"parts of objects cut away with the global clipping planes in Chimera  
will still be shown in the raytraced image"

However, you may be able to get what you want using Per-Model  
Clipping (under Tools... Depiction), as that type of clipping is  
translated into the information sent to POV-Ray.  Here are more  
details on using that tool:
<http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/per-model/ 
per-model.html>

I hope this helps,
Elaine
