Moving skeletal mesh bones

I want to do a 4W vehicle that behaves like a tank, but that is not possible with a simple wheeled vehicle Blueprint. This is what I tryied, but nothing works:

This is inside of my pawn blueprint. I have no Idea what to do next, as it does not work as is. Does it have to interact with the animation Blueprint for any transform to be given? Because I need to rotate my wheels from an input and that does not seem to work inside of the animation Blueprint (I’m new to skeletal meshes).

you can rotate a bone via animation blueprint (use the transform bone)- just transfer the value to anim graph and you are ready to go.

How can you do such a thing? I don’t know how to transfer a variable from one blueprint to another. or is it just a value you transfer?

Thanks for your time

As mirsabayu said you need to use Transform(Modify) Bone function in Anim Graph of the anim BP. You can transfer values between BP’s with a BP Interface.
