Regression

No

Animation playback and transitions start being erratic when state normalized time gets too large with no indication what is the problem

-

How to reproduce:
1. Open the “AnimationTest_250618_ETimeOn_2021.zip” project
2. Open “SampleScene“
3. Enter Play Mode
4. In the Edit > Project settings > Time, change the Time Scale to 100
5. Select the “PJPCumulative“ GameObject in the Hierarchy
6. Wait ~1 hour
7. Afterward, change the Time Scale back to 1
8. In the Animator window, change the 'Lvl' parameter to 2, and observe the Animator and the Game view and the Console

Expected result: An error, a warning, or a log is thrown in the console informing about this behavior
Actual results: The active state does not change to the corresponding state (unless 0 or 7 is put in 'Lvl' parameter), the Sprite size does not change, and the Console does not output anything

Reproducible in: 2022.1.0a1, 2022.3.64f1, 6000.0.52f1, 6000.1.11f1, 6000.2.0b9, 6000.3.0a1

    The resolution of this Issue created a problem as reported by: https://issuetracker.unity3d.com/issues/animator-is-still-spamming-too-much-when-states-stay-active-too-long

    However, for whatever reason, 6000.1.x was missed? 6000.1.17f1 was the last 6000.1.x release, and it has severely degraded performance at times because of the log spamming from AnimationController.

    This fix has severely degraded performance and made the game unplayable and the project impossible to work in due to the continuous log spam. Please address asap.

    Just ran into this issue with a short non looping Animation that just set's the state of an object and does nothing afterwards. After around 10-15 minutes the console log goes balistic because of this and it totally tanks our FPS. I'm not even sure what I should do to mitigate this. Write a script that reset's every animator state every 10 minutes? Please give us an option to turn this log off

    The fix for this issue caused a regression that ruins performance due to excessive error logs. 6000.1.17f1 is unusable because of this.

    Please fix this with urgency. We cannot take important security updates because of the excessive amount of log spam.

    Our logs are being spammed by multiple animators when we have a looping idle animation state (e.g., for a UI button) that consists of only a few keyframes, and the game is often running in fast-forward mode for a long time.

    This issue has completely blocked us from upgrading to the latest Unity version, which contains important security fixes.

    Mostly looking at the issue you guys went overboard with the threshold. It says 100 x timescale over an hour. So basically a 100h session.
    Don't flood my console at 5 minutes in.

    Nice to have warning. Should only trigger once or something. Adding an other voice as to the regression that floods the log. It should be an opt-in.

    This fix is still generating far too many error logs even in Unity 6000.0.57f1.
    As others have suggested, this fix should be reverted, an option added, or improved in a better way.

    It still occurs in Unity 6000.0.57f1.
