Issue with animating bone in AnimationSequence Editor

No problem.

Thanks for the file. I was able to load it onto the UEFN Mannequin without any issues. That said, I couldn’t reproduce the problem with just the animation, which is where I initially thought the issue might be, so there may be some more back-and-forth here. My thought is there might be something unique about the newly skinned mesh or the approach you’re using to attach the hitboxes.

  • Having the skinned mesh as well could help.
  • Could I get an overview or file explaining how you set up your hit boxes?

When you’re editing your attach bone, just to verify you are:

  • Selecting the attach bone
  • Hitting the key button
  • Animating on an additive curve
