Spring arms never worked as intended and they never will as i discovered trough many many threads. It is a common UE issue that is carrying all over and one of the most importants issues people encounter when making NON first person based games. No matter what you try, you will always get clipping, even if the spring arm is supossed to mitigate it, this is completely obvious using a third person template when you rotate the camera. In first person shooters is not really noticeable because the camera is basically snapped to your character. The only option that could work in the case of a third person template is to make the walls and other objects thicker, so the probe cant pass through the object. But thats about it. Im still, after so many years waiting for Epic to actually fix and improve the spring arm system so we can actually make decent third person games. Still no luck. Thats the main reason i NEVER EVER start a third person project. Its completely annoying and unacceptable. In the cases when you will walk over a building, and using doors and small apertures, its going to be a total mess. And it looks terrible. Unfortunately UE is designed for first person shooters and no much more, sadly.
