Having an animation override track clip ease out causes the character to fly away

Unity Engine

I cannot tell what is wrong with this. I use the basic Unity Sample Scene and Pxltiger’s Zombie. I have a basic timeline which plays animation for the zombie and then an override track using a different animation. The override animation track has an avatar mask which includes ONLY the head. So rest of the override track animation shouldn’t affect the Zombie’s body.

This is how it looks when playing in edit mode:

Works as expected. However, this is what I get when I start play mode:

It’s tougher to see in the gif but the Zombie just flies away during the clip ease out. What is causing this? Bad setup? Unity bug?

I don’t know the answer, but I would investigate “root motion” for the first video and “scene offsets” (right click on track to adjust track offsets). I would single frame step on the second to work out the new value it is blending to. Maybe you need to drop an animation clip to blend to… (just suggestions to explore, not solutions sorry)
