I’ve been in the process of learning Unreal 4 for class designing a game for the last few weeks, and
I had a problem recently that may save someone else the trouble of figuring this out.
If an existing moveable object, in this case a blueprint Static Mesh Key with a collision box, has Block All assigned to Collision on both the Collision box and the Static Mesh, all moveable objects now somehow have no collision at all.
I didn’t need collision to be this way and had set it earlier while figuring things out only to forget about it and have this problem later. Why does this happen?
