The custom humanoid physics controller thing is jittery. The code doesn’t even matter, nor does the camera scripting. In fact, no scripting matters. This example could’ve been shown if I just used the explorer properties. The camera’s camera type for both examples is just track, with the subject being the root part.
Standard humanoid: smooth
Custom physics controller: jittery (in the video it’s kinda hard to see but it looks choppy)
Again, it is kinda hard to see, but it’s extremely noticeable when playing, because the lines just look blurry.
