(Angel,
sorry for having taken your time, I was desperate for an immediate
solution but it later all worked out, with some specialties because of
the Mac machine. I've Cced the list, as it all wasn't easy to find out.)

Actually, the only working solution to get molecule/surface data into
Blender is to use the script at
http://sourceforge.net/projects/vrml97import/
That is the only Blender script capable of reading VRML 2.0 aka 97.

One dependency you might need is
http://simpleparse.sourceforge.net/

On the output side with Jmol, the popup menu's save/VRML 3D model
does it all, and I have no complaint. Thanks to the author/s!

For a stress test, I tried the polymerase-II dimer in PDB 3HKZ with both
CPK and an isosurface. That gave me a 30 MB VRML file. After renaming
to .WRL, blender took dozens of minutes to fill 500 MB of memory, and
that was the point I killed the process. Probably the CPK takes (gasp!)
even more memory in blender than in VRML. A surface only file of PDB
5ACN had no problems.

Best,

Ralf Stephan
