Hi Tom, welcome to MoI!

MoI has a pretty different modeling approach from Cinema4D, you may find it especially useful for building industrial or mechanical type shapes quickly, with precision. Like Pilou mentioned, use OBJ format to export models from MoI into Cinema4D.

No, not in the 1.0 version.

Could you please attach the file here or send it to me at moi@moi3d.com so I can check it out and see what might be going wrong?
