I am using Carrara for the render, exporting from MOI using .obj, the .3dm import in Carrara also works great. I used .3dm for the spark plug, x-box, coffee pot, and headphones. A good renderer for the cost.

Michael - Would it be possible to add a toggle that would flip the lighting in the display. Sometimes the shadows obscure the model at certain angles, it would be nice to be able to hot key and flip the light source to the opposite direction.

Also what would I need to make a shortcut key for "make corner point" toggle when drawing a curve?
