Hi, you can import a collision mesh from blender and use that. Otherwise you can build your own custom collision via primitives in unreal engine. If its really low poly you could also use complex collision (per poly collision) as simple. If you just import a cube with one face missing into UE, the collision UE automatically generates will be around the whole cube.

so. I make maps in blender because the Unreal build tools are so confusing to use, and of course, the first thing I did was create a “Hollow” cube (Basically a cube with a face removed to make sort of an entrance kind of thing) my question is, how to I remove collision on the open face, and ONLY on the face in ue4?

in blender the face is open and I can go through it. but in unreal, I cannot go in it. I even turned on the player collision view mode to see if it had collision, and it did. the view collision showed it not having collision though, so there’s that.
