Replying to my post here:
I figured out how to deal with this. Because of scale issues in Blender there are two solutions.
1. after import via CC-pipeline add-on, join all the meshes into one monolith and bake materials to one texture set (an atlas) if multiple sets.
or
2. on import via the CC-pipeline add-on, also check Rigify. Then retarget and bake the motions.
Cheers!
