Hey ive just started using your plugin and have been wondering how to connect an armature/mesh to it. Any easy ways of doing this? Thanks

.c3d files are raw motion capture files they do not describe a skeleton armature directly as the data only contain recordings/samples of motion capture markers which are placed on the skin surface of the actor. To actually get a connected armature which can be used in a similar way to a character rig 'to animate meshes' one has to reconstruct the motion by fitting a musculoskeletal model mapped to the points. The purpose of this addon is primarily for the purpose of importing .c3d motion capture data in Blender either for:

as I don't know tools currently available in Blender for the second use-case there are paid software's such as MotionBuilder with a free trial (if there is a limited set of motions to convert). There might be better options but MotionBuilder will get you there.

I know this reply is a bit late, but there was similar questions in unrelated threads and this needs to be clarified. I will keep this thread and retain it as a FAQ.
