I was using UE4 the other day and playing with the FPS template level, and I made a couple of spheres that would bounce and move around when shot just like the cubes in the level. However when I opened it up today it would just open up a mesh edit window with different tabs, images to show what I mean. I could open it for the FPS projectile but not the actual spheres I placed int he level before.
How I want to open it
How it opens now
