Skeletal mesh has no collision against landscape and static meshes

Basicly, actor made of 4 parts:

  • Body
  • Real Legs
  • Fake Legs
  • Physics constraints

I wasn’t been able to make skeletal mesh collision work.

So I made Physics Legs connected by Physics constraints to the body, and driven by Physics constraint motor.
Fake Legs just a skeletal mesh without collision and IK to Real Legs.
