Changing Character Head Bone scale

Hello. I need to change the scale of my characters head as its to big to fit correctly to Match the other mesh It is grabbing the master pose from to use.
So I thought I would try and change only the head bone scale in the anim BP, But its not changing the head mesh size in the character BP ?
How could I pull this off?


You don’t see the Transform Node scale because you’re not in Play/PIE mode, adn as far as I know you won’t be able to see the effect in the BP.
If instead you drag/drop your character in a level, then use the Play/PIE mode, you can check directly there to see if the head fits or not, and eventually you can update the AnimBP values in realtime and compile it, you’ll see the update while in Play mode.

I already tested It In play , and the head scale is not changing scale :(.
Update I think I found the issue . Because Im using set master pose to put the head in the correct place on the animated body. Its overriding the Bone scale I set in the animBP.
BUT I NEED THAT MASTER POSE so Now Im a bit stuck on what to get them to work together
