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. Tom On Mar 12, 2013, at 11:01 PM, Maja Divjak wrote:
Hello Chimera,
I would like to export some protein models in obj format and I was wondering if there is some way of reducing the mesh complexity when I do that please? 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?
Thank you for your time,
