There are various settings which can increase the number of triangles. For example,
 
set surface_quality, 1
set cartoon_sampling, 20
 
However, PyMOL is for the most part simply outputing the geometry it uses internally.  So if your VRML viewer can't do as nice a job with the same geometry, then what you're seeing may be a shortcoming of the VRML viewer rather than of PyMOL.

Subject: [PyMOL] .wrl Export

Hi,

I have been exporting .wrl files from PyMOL but notice a distinct lack of quality in the files when opening in other 3D visualization programs.  Are there any ways to increase the general quality of the model for export that I am missing?

Thanks,

Paul
