I follow the doc Hair Rendering and Simulation Quick Start | Unreal Engine Documentation to learn the new hair system.Everything is fine except the Bind Groom to Skeletal Mesh.
When i enable the this option ，My hair always disappeared like this.
The mesh created by daz3d G8F.And hair attach to head bone.
I think maybe something wrong with the girl chracter. I try to use the UE4 Mannequin mesh.The same problem.
If i don’t check the “Bind Groom to Skeletal Mesh”,everything is fine.
So,how do i fixed that problem ?Any help will be appreciate.
