I have a similar issue as described above. Normally, when walking up a slope (terrain or 3D object), the walking animation has always been very smooth in my game. Now, all of a sudden, it's very choppy and I don't know why. I created the video below to show the difference. I've actually not made any significant changes to the character itself, and also, it's happening across all my scenes. Every scene has its own character, so it's either something that I did in every scene, or it's a global issue. I recovered an earlier version of the game to verify it's a problem that previously didn't exist and used it to produce the first half of my video below.
I've already tried changing the Motor Slope Force Up, but given that I never changed that value in the first place, it wouldn't make sense to change this value now, the problem must come from somewhere else. I tried changing this factor anyway, which reduced the choppy effect a bit (not fully back to normal though), however, at the same time it caused my player to run up slopes much faster than when walking horizontally or walking down a slope, which is not realistic, hence I prefer to find the actual problem that causes this effect.
So I wonder if anyone has experienced this before and has advice on how I can revert this effect. Thank you so much
