But when i pluggeg there ,nothing happens ,no reaction of BP I mean It does’t cast to ,I followed the debug signal goes till “set active anim child”.Thanks anyway for great solution now I know how to get external reference in my level BP, now I need to figure out why nothing happens when I cast to set active anim child.
