[Chimera-users] converting a pdb to surface, then to obj

Hi Dave,

  Yes, exporting surfaces from Chimera in Wavefront OBJ format does not 
include colors for multi-color surfaces.  You have to export VRML, X3D, 
Povray, or Renderman formats for that.  I know some people export to 
VRML then convert to OBJ with other software for import into Maya, but I 
have not seen any case where they carried the Chimera colors into Maya.  
If you figure out how to do that I'd like to hear about it.
