I am not certain if this is already a functionality of the plugin (still experimenting), but what would be a huge help would be the ability to either use a region based or even poly face selection that would allow for ONE dmm object to have multiple material properties.

IE if I were to construct a model of a building and have it be one solid piece (for whatever ridiculous reason) I could select the region of the model where the windows are and apply a glass material and immediately next to that concrete.
