I have iClone 7 and 3dXchange fwiw --

In the past when I have rigged a character in Reallusion programs, given it some animation, then tried to export for Blender, the bones of the armature become disconnected from one another, and more importantly, it seems to lose all IK bones. So basically, a simple walking animation done in iClone becomes impractical to use in Blender because there is no way to set floor and collision parameters.

I know I'm doing something (everything) wrong, and could really use some advice on how to get this pipeline working as it should!
