Using UE 4.7.5 I’ve created a simply blueprint using a static mesh set to simulate physics and then spawning it in the world. For some reason the collision only works occasionally as shown in this video.
I’ve also tried simply placing it in the world via drag and drop to see if it was the way I was spawning the actor. Sadly its not. Don’t know why this would be. I also tried removing the collision from the mesh and switching over to box instead of capsule. Didn’t help.
