I’m far away from the UE Forums, if you get trouble can send me the mail: daosuiban@gmail.com

1. create a control rig BP(Blueprint) and an AnimInterface BP
   

   

2. In ABP Anim Graph create a control rig node and set the CRBP which just created, then connect the input pose and output
   

   

3. In CRBP, create “Set Transform - Bone” node, and most important thing is, uncheck the property “Propagate to Children” !!!
