MyAnimationSharingStateProceessor:
349523-
ActorBP:
349522-
setup as ue‘sDocumentation,and it’s work!!!
349524-
but, when i change the actor’s Skeletalmesh ,it isn’t a result that I want。
349526-
that two skeletal use the same skeletal (Als_Skeletal)
349525-
, and I set skeletal retargeting:
349527-
.
the difference is size (Short Stocky ,Tall Skinny)。

when i just change the animationsetup _SkeletalMesh:
349528-
the result is this:
349530-
So, I need some help , because I study UE4 just 8 mouth as a Rookie。
