Send to Maya

Coding Python Support

Hi,

I wrote this script snippet a while ago to speed up my workflow between Blender and Maya. It essentially sends all selected objects to Maya via OBJ export.

I came back to it recently and thought about expanding it and maybe offering the export format to be FBX instead of OBJ.

So yeah, I would just like to know what you think of the idea and what you would expect from such a script.
