I want to create my own rig name for Tool preset where character were export to. my client use their own rig that they want me to use and add mesh it it. I cant be a___ to skinning and rig it per items ( yeah more than ten! maybe fifty!) and I cant use retarget as it have to use client's custom rig (all it do was change name of bone.)

How can I do that within Reallusion software across iAvatars?
