Editing Vanilla 3rd P. Animations Not Working Right.

[Malfatto]

Hello.

I'm editing some vanilla 3rd person animations, in particular adding NPC animations to Onymaru's pistol animation mod, but the animation is not working right. I only edited the position of arms and a little neck and chest twist, other than that I didn't touch anything. In the video below I'm testing the RelaxedTurnInPlaceRight180 and RelaxedTurnInPlaceLeft180, because these don't have annotations so it would discard this as an issue. The best I could do is at the time of exporting from 3DS Max, in Havok Tools, allowing only Turn Motion, and Reference Frame Type: Move/Turn, in Extract Motion step.

Is there something I'm missing? Anyone have a tip?

Here is a video showing first the animation I edited and second the vanilla animation. Notice that in the edited animation Piper skids and skip animations. It is just odd. The vanilla unnedited animation is fluid.

Thanks.
