Eyes Shake and Look in Wrong Directions When Animation Exported To FBX
When I animate a character in iClone 7.83 using face expression keys and LOOK AT CAMERA or PICK TARGET for eyes, the animation looks very good in iClone. However, when I export the animation to FBX, the eyes go crazy (vibrate, look in wrong directions, jiggle, etc.). This also happens if I try to save the animation to a motion plus.

VERY EASY TO REPRODUCE:

1. Take a character.

2. Add a motion from the library where character's head moves.

3. Add some expression face keys (this is optional, it happens even if you skip this step).

4. Use the LOOK AT CAMERA function, or alternately, use the PICK TARGET function and have character look at a target.

5. At this point, eye movement should look correct in iClone.

6. Export an FBX using the Auto Setup Unreal Engine settings

7. Import the FBX in Unreal Engine using the correct Reallusion set up tools

8. Add the animated FBX character to a scene, add the animation to the timeline, hit play.

9. The character will animate correctly but the eyes will malfunction (go crazy).


IN ADDITION:

This also happens within iClone if you save the animation to a Motion Plus

1. Animate your character as above, and add the LOOK AT CAMERA or PICK TARGET function

2. Do a collect clip, and save the animation to the library as a Motion Plus

3. Do a remove animation from your character, make sure timeline is completely empty

4. Import your saved Motion Plus animation (that you just made)

5. Hit play and the eyes will malfunction (go crazy).

PLEASE FIX THIS!

hi this issue also replicates in iClone8 exporting usd to Omniverse.
@Daymos_Visuals 
Any updates to this issue?

I'm also having trouble exporting blinks (created manually) as the eyes just stare.

The eye ball movements work in iclone but barely m(along with the jitters or cross eyed stuff mentioned above) but i can handle that if i can get it to blink.

Is there any manual work around to not get this issue?

Yes, hard to believe this is an issue. Point At seems like it should be a totally baked-in function. Poser & Daz never get this wrong.

Here is a video that clearly demonstrates the bug. The character is set up to track a dummy object (using PICK A TARGET) that is keyframed back and forth, left and right. The eyes bounce and jitter, and look in different directions as the head tracks the object. Please fix this bug ASAP! Thank you.
