Is there a particular reason why I can not import *.iCloth files - exported from my Character Creator 3.01 character, into 3DXchange 7.5, yet it works for *.iAcc files. I want to import *.iCloth files into 3DXchange, in order to export them as FBX format.

Ideally I would like to be able to directly export anything selected inside from Character Creator 3 to FBX format.

Why does it make sense to export cloths from my character to FBX?
Since these items appear to be already rigged to the character, I would like to add, and or remove items from my character in-game, using Unreal Engine for game development. Additionally, this appears to be a major feature game developers everywhere crave for.
