I agree with you Michael that moi should be focused mainly in modeling. It would be good, anyway if will be possible for someone to develop some sort of exporter, in order to better interface with the rendering software. Something similar to the exporter for Octane (a sort of Moi2Octane...).
I attach two screenshots from the max version, obviously some part is not applicable (animation, ...)but something else can.
I know that we can do the same via OBJ exporter, but it's better in this way. One problem here is that usually this rendering application need an already UVMapped geometry.
