used blender and made a UCX_ object with a torus mesh and once I have put it in ue4 it just fills in the middle and I can’t get through it. Any way to fix this?
That only works for static objects. If you have objects that simulate physics, it won’t work.
Have you tried link?
Other than that, the only thing that comes to mind is simply having a lot of UCX boxes on your torus.
