Marvelous Designer 3 and Carrara Via Fenric's MDD Plugin
After much hand wringing and gnashing of teeth I found a thread describing how to get the garment animation from md into carrara 8.5 with the MDD plugin.
From MD3, Export MDD Standard: single object, Welded. (also check the unified UV's option, It makes retexturing the object in Carrara easier)
In Carrara 8.5 (as Fenric Described for 8.1) New File: (clean, without other objects in the scene) Import .MDD file.
I found that once you get the MDD into carrara, if you save it as a .car, you will then be able to import it into another scene that has an MDD file already in it.
You'll have to re assign your textures/colors in Carrara. The file should come through with shading domains intact. If you are using a texture map, exporting from MD3 with Unified UV's then your UV map in carrara should look like your pattern layout in MD3.
