[PyMOL] getting pov-ray temp files

[Bhyravbhatla, B. <Bal...@um...>]

Hello All,
I am trying to render a large mega Dalton complex and can get it up on
the screen but rendering it causes a crash because of memory issues (I
have 1Gb on the system and tried on a 2Gb system also). So what I would
like is to get the temp pov ray files that Pymol is writing out and use
those with PoVRAY.
I am unable to find the location of those files. Can you please point me
to where they are written?

If anyone also has ideas on how to get a decent publication quality
output for a complex (think in terms of viruses) that would be helpful.
I do have a session file saved with my views.

Thanks

Balaji
