Capsule component of my zombie character falls on side over time. Walking and running animations have a root motion enabled. Physics simulation isn’t turned on. The problem could be fixed if controller pitch, yaw and roll rotation set but they need to be off for the smooth rotation towards player. Here’s a link to the video with problem: https://youtu.be/_inPfdvN5RE
Hey @MrBeer02! Welcome to the forums!
So what I’m thinking is you’re having the X and Y rotation turn towards the player as well, when it should only be the Z turn. Would you mind showing us some of your code so we can help you pinpoint the issue? Specifically the rotation code and the nodes before would be great! 
This happened for me as well. I manually set the yaw every tick so that they don’t fall
Hey @MrBeer02!
Did you ever get this figured out?
Let us know what you did, or how it got solved, or if you still need assistance with this, we’d be glad to help out!
