I have a hip holster asset on my character that has some shape keys to help with clipping during locomotion.
I added an animation curve to the locomotion animations that drives the shape keys for the holster mesh. But it only works if I play the animation directly on the holster skeletal mesh.
But the anims are playing on the main character mesh and the holster is a child, hooked up via the leader pose component. So it doesn’t deform because I’m guessing it can’t “see” the curve from the animation playing on the parent mesh. It just follows the pose I guess?
How do I get around this? I want animation curves playing on the parent mesh to drive shape keys on a child skeletal mesh.
If anyone is looking for a solution to this issue, what worker for me was disconnecting the holster mesh (child of the main character mesh) from the leader pose in construction script. I then created it’s own animation blueprint, get a reference to the player mesh in that new anime BP and used a Copy Pose From Mesh node in the anim graph. That node will essentially drive this asset with the same animations as the main character mesh. In that Copy Pose From Mesh node is a checkbox to “Copy Curves”. That made it so this child skel mesh can be influenced by curves from the parent mesh.
Hope that helps someone if this comes up in the future!
