Made a blueprint which creates tunnels. The collision is made up of simple box shaped meshes 4 sections each for walls on each side, floor and ceiling (16 hulls in all). The collision bends along with the tunnel as expected.
Collision node is present in the blueprint and is set to collide.
Collision works fine for the character but the third person camera goes right through it.
You must edit you geometry in Unreal Engine, in the section of:
collision>collision complexity
chose:
âblock allâ
âuse complex collision as a simpleâ
