I’ve messed around with a lot of different things since then, and had marginal improvement. The distortion issue seems to occur when the animation is exported as Additive (like it’s supposed to be).
If I turn off the Additive option then it looks OK by in the preview. But in the game mode using hte state machine results in the character moving wildly off the screen and a warning appearing that it’s meant to be additive.
If I Enable Root Motion, the first time the animation plays in the Animation preview it shows the character flipped forward on it’s face. Then the second time it plays standing up. Unfortunately using it in the game just plays the first animation and the character lays on the ground momentarily.
After trying a ton of combinations in the Additive and Root Motion options I’ve finally found one that I think might work. I compared the exported animation to the original and found some settings that were different.
I have it set to:
- Additive Anim Type: Local Space
- Base Pose Type: Frame from this animation
- Ref Frame Index: 26
That fixed the distortions.
But I had to set these for the animation to actually work:
- Enable Root Motion: false
- Root Motion Rook Lock: Zero
And the animation in the preview was on it’s back. But this fixed that issue:
- Force Root Lock: false
Now the animation works in both the animation preview and the game mode.
