I know I can always just use a plane with the “Use Complex as Simple” option enabled for collision, but is there any way to import a plane as collision like the UCX_(RenderMesh)_## format? I have been using the method where I add a plane and set its collisions to use complex as simple but I would like to be able to simply import the mesh with the one-sided collision already intact. For instance, I have a gate that has two convex (UCX) collision meshes for the pillars on either side and a plane in the center to act as the one-way barrier.
i dont know how to set meshes up with one sided collisions like that, but alternatively, through blueprints you can setup a box trace in front of the mesh on the side that will block the player. if the box trace hits the player, activate the colliders on the mesh. if not, disable the colliders.
