So far the only answer I have found to this is that you have to have added the actor to the level for it to be constructed at level load or else the physics won’t work in the packaged game.
So you can add the character to the scene, then possess it and modify it from there.
Thank you for posting the solution to this problem!
I’ve tried adding the whole actor versus adding a single strand of groom asset in the level, both methods seem to work (groom hair physics simulated without problem) in packaged game.
Please help. When simulation is turned off, the hair groom looks fine but as soon as I turn on the simulation, the groom goes all up and stays there. Attaching the screenshots. Any help would be appreciated. I checked the collisions, skin cache but nothing is working. Its a custom groom from blender.
