[Chimera-users] Reduce mesh density?

Hi Maja,

  Chimera OBJ export cannot handle molecular models (ribbons, spheres, sticks…).  So I guess you mean surfaces.  For a Chimera molecular surface there is a "vertex density" parameter that you can set to a lower value in Favorites / Preferences / New Surfaces… before creating the surface or by selecting the surface and using the selection inspector dialog (Actions / Inspect, MSMS surface).  The default vertex density is 2.  For density map surfaces you can set the step size in the volume dialog to 2 (use every other data point).  For surfaces made with the molmap command you can use the gridSpacing option.

I am using the models for animations in Maya and when I use the mesh reduce feature in Maya, Im getting some rather odd results, so was wondering if I can actually simplify the models first in Chimera?
