Seems like wrl2ma has a limit on how many vertices in a surface it can 
handle.  Try reducing the vertex density of molecular surfaces and see 
if that helps.

There is also the chance that is it a bug in Chimera's VRML export. So 
first, update your Chimera to version 1.8 and check again -- the bug may 
have already been fixed.  Next, try viewing the generated .wrl file with 
a VRML viewer, e.g., BS Contact, Octaga Player, or Chimera!  If it 
displays correctly, then the bug is Maya's.

If you do submit a Chimera bug report, please include a Chimera session 
that will reproduce the error.
