Because there is no LIVE LINK for UE5 plug-in. So I exported the character from UE5 as FBX(This character is from UnrealMarket). Then import 3DXchange7. And set up all skeleton correctly.

Then I send to iClone7 and set the animation. Finally, I export the animation as FBX.  

But, when I import UE5,And select the character's skeleton(The character's own skeleton) in UE5.

It shows the multiple skeleton mismatch.

How to ues iClone7 and 3DXchange7 for UE5 own character make animation without LIVE LINK plug-in？ 

Thank you for your answer
