Humanoid rotation issue

So I have two animations. The ending state for the first animation is the same as the starting state to the other.

When the rig is set to humanoid, for some reason it thinks the poses are different - but in the modeling program they are exact copies!

As you can see in the video - the guy swings his sword and then his hand rotates back while interpolating between the two animations - but why?? The two poses are exact same!

This only happens if it is set to humanoid. I am using Blender.

Video to illustrate the issue: https://www.screenr.com/jOcN

seem like the conversion from euler to quaternion made by the importer to resample the clip take two different path for the same euler configuration hence why you ended up with this gimble lock issue when blending both clip.

Can you log a bug with a project with these two animation files and your controller. PM your case number when you get it.

Best regards,
