Hi Nicholas, The ChimeraX OBJ reader is all in Python with source code included in the distribution.

Hi,

I took ChimeraX for a spin and when I save out to OBJ, the geometries looks connected up wrongly.

I was hoping I can take a look at the source code to attempt to fix it myself.

I see git being mentioned in the documentation. Is there a git repo I can clone and contribute to?

If I need to sign any documents before contributing, let me know :-)

I have other geometry format I'd like to write out to and also I am hoping to write out quads rather than triangles for use with OpenSubdiv in rendering software like RenderMan, Arnold, Mantra etc.
