Kawaii Physics collision with two separate skeletal mesh

[unreal0924]

I decided to have hair and body as separate skeletal mesh. Kawaii Physics worked perfectly fine when I had my hair as part of body mesh but I can’t figure out how to add collision so that the separate hair mesh does not penetrate body mesh. The hair mesh penetrates the body mesh because the kawaii physics of the hair skeletal mesh does not have any bones that can be used as root bones of the collision capsule/plane. In AnimGraph there is an option to add additional skeletal mesh to preview scene and I can somewhat use that to draw the collision spheres but because animBP obviously doesn’t recognise them as part of the skeleton the spheres are not linked to bones and will always stay in T-pose no matter what animation is being played. Is there any way to make this work using Kawaii Physics? Any ideas would be very much appreciated. Thank you in advance!

I also have a separate skmesh for hair, but mine has dummy bones that track the head/shoulders etc of the player. Took the idea from the ue5 valley of the ancient demo character setup. Appears to work as expected.

From what I know, when you're setting it up like that it's a good practice to have the skeleton on the hair mesh as well (or at the very least the hierarchy till it reaches the hair, even if they are nothing rigged into that. You must NEVER make a spaghetti with the hierarchy and make each one have their own pathway till the root for characters). You should make the hair a child of the body inside the blueprint and them use the body as the main body driving the animations. I think it's like 3 nodes to set this up. Check how Epic do that with their own Metahuman characters.

I used Echo from the Valley of the Ancient Demo as ref. Set the 'hair' skmesh as child of player skmesh. Give hair skmesh a simple ABP that uses the Copy Pose From Mesh node set to 'attached parent'. String in your Kawaii goodness.
