Collion problem when importing a simple room from blender

I’m guessing this is simple but I just can’t find the answer.

I’ve got a cube in blender that is going to be a room the player can run around in. I switched the normals to be facing inside. When I import it in UE4 I scale it up and add a simple box collider in the static mesh editor. Then I drag my player inside the box but I get a warning with “Bad size” on it. When I hit play I start on top of the cube.

I’ve tried a few different things:

  • Setting the import size when I export of blender instead of scaling UE4: no difference.
  • Switching the collision mesh to convex collision

Does anyone know how I could make this work?
