AC 1.39 camera jitter with UFPS.

Vadbag

After the update to 1.39 I got camera jitter problem with UFPS, but the script execution order doesn't help.
Once my character walks up a staircase everything starts to shake and
then gradually returns to normal until I try to walk up the stairs
again. Also, the jitter occurs while walking on the flat surface, but
not as bad... Furthermore, I found that the jitter disappears if I
have the Camera&Controller object in the scene, but once I delete
it to use Player Prefab, the jitter is back.

If the Camera&Controller prefab gives you better results, have you tried converting it into an AC-compatible player?

Vadbag

It is the same jitter with any UFPS prefab if I delete it from my scene and leave it as a prefab in Resources folder. There is no jitter if I do not delete the controller from the scene. However, before the update 1.39 I did not have this problem, even when I just had player prefab in Resources folder.

Perhaps this issue varies from computer to computer - some reported the jitter effect went away with 1.39.

The source, I think, is in the MainCamera script.  Open it up and change the LateUpdate () function (line 364) to Update ().  Does that solve it?

Vadbag

No, not really... Can it be something to do with loading the player prefab from outside the scene?

In my case this was solved by doing it the other way around: changing the Update function into LateUpdate. Also check this thread.

@Morphweasel: The Update function in which script?

Morphweasel

Sorry. The StateHandler script; like you advised me in my camera jitter problems thread

ChrisIceBox

@Vadbag: Try @Morphweasel's suggestion - does that solve the issue?

Expect this fixed in 1.40.
