Setting vars in the AnimGraph of AnimBP via Interface - not possible?!?!

Is it not possible to use BP interface to set values on variables in the animBP’s AnimGraph without using EventGraph ?! Casting works fine, but I’d like to use BPI instead and it doesn’t seem to be working at all :confused:

If you implement the BPI on the animation blueprint with custom functions, wouldn’t it be the same as having things in the event graph?

you would need to implement it on the character with the same functions…
