Hi.
I created a simple blueprint actor with a couple of poseable mesh components. I created some variables and used Set Bone Rotation by Name in construction script to set some bones rotation. Everything works hunky-dory in the editor but when i hit play everything reverts back to it’s original state. And in play mode when i eject and select the actor and change the variables everything updates to what it should be.
can you tell me the hierarchy of your skeleton example:

I suggest trying to set the bone rotations in a BeginPlay event rather than a Constructor, or have both events run the same function which does the bone setting.
