Thanks that has actually solved the problem. I just worry now there may be another problem that can only be fixed by increasing position smoothing. For example, will this effect moving up and down stairs? Currently my character can move up and down actual stairs nice and smooth without the use of a "ramp" collider and without the camera bouncing as it follows. Without position smoothing, will it start bouncing as the character moves on non-smooth geometry?
(I'm just guessing at what position smoothing actually does btw, so apologies if I'm wrong)
