Maybe, I’m not sure I follow completely but as far as referencing the anim BP maybe. In the situation above I had a class, that class had a mesh with bones/ animations so I created an Animation BP. I was trying to get my class to talk with the Animation BP. So in my class I there was the component variable “Skeletal Mesh” in the window where you create variables. So I “get” the skeletal mesh variable in my class BP, and from that node I “cast to” my animation BP - which should be listed. From there you can get/ set any variables within your Anim BP from you Class BP.
