[5.2.1p1] Problem when mecanim animation on the first frame

Something that worked for me is to set the Update Mode as animate physics. Is not exactly the last frame (in my case) that blink, but was really annoying.
Version 5.3.4

 

We are also getting this bug in 5.3.5f1, I have managed to create a simple project which reproduces the issue, it seems like a very specific set of circumstances that causes it, I create prefabA at runtime on a button press, this prefabA has a script which creates prefabB in Start(), prefabB then creates another AnimatingImage prefab in Start(), the image flickers on before entering its default animation state which sets the alpha to 0. If I move the prefab creations into Awake() the bug goes away, if I remove a layer of creation of prefabs it also goes away.

It's not exactly how we do it in game, we have our prefabs created on animation events but we require a fairly complex setup of prefabs due to what information is available to us at specific times. I shall create a new bug and attach the SimpleProject.

 

Here is the bug https://fogbugz.unity3d.com/default.asp?800969_ve7k62bsqoe976lg

 

I have found this bug in 5.4.3f1.

It occurs when the animated object is instantiated in response to an animation event. I've reproduced this behavior in a separate project.

My workaround is to wait until the next frame to insatiate the object. I did this with a coroutine:

Code (CSharp):

1. public void AnimationEvent () {
2.      // instantiation here causes first frame glitch
3.     StartCoroutine(DispatchAnimationEvent());
4. }
5.  
6. IEnumerator DispatchAnimationEvent () {
7.     yield return new WaitForEndOfFrame();
8.     // safe to instantiate
9. }

I hope this helps someone, and it gets fixed in a future version

 

I have submitted a bug reported as you asked. Case number 858285.

 

Any update on this? Using Unity 5.6.0f3 and the issue still persists. Using the animator to enable a child gameobject that contains it's own animator results in the child flashing before proceeding to the first frame of its animation.

edit:
Like a prior user suggested, a temporary workaround seems to be to set the child animator's update mode to 'Animate Physics'. Note that if the parent is also set to animate physics, the solution no longer works.

 

This is the response I got from the Unity team:

 

Same issue happens if the prefab is instantiated as a response to a received network message (such as a RPC invocation). The animator.Update(0) is also a valid workaround in this case.

 

I have the problem in unity 2018.2.11f1.
animator.Update(0) in OnEnable does not solved it.
I see the previous animation at first and then the current animation.

 

I solved it. It was annoying.

Code (CSharp):

1.  
2. _animator.Update(0);
3. _skeletonAnimator.Update();
