Workaround for Tent Idle Animations Deforming Character's Face

Extract the zip into your MHW folder.

I was able to boil the issue down to the X position basis value of bone 251 in each of the animations. Which turns out to be an index to a facial animation, stored in pl/common/face_mot/pl_face.lmt.

So then, this fix (mitigation) works by reusing non-broken facial animations (199, 317, 106) to replace the broken ones (112, 104, 105). I tried to find animations that match up as best as possible, but it's far from perfect.

As you can see, the broken animations are still obvious when inspected in blender. They seem to be based on a different head shape or something. I made an attempt to directly fix the broken animations using a script that parses the animation file. I got decently far by copying the per-bone adjustment values from a non-broken animation and working backwards from the first keyframe to create the basis value. Ultimately though, there was still obvious visual issues with that approach.

You can see the work for that here and the resulting pl_face.lmt, if you want. https://codeberg.org/pizzabelly/MHWNewCamera/src/branch/master/Research

I wouldn't have been able to figure this out without MHW-Free-HyperKinetics, credit to AsteriskAmpersand.

Based on co00_03.lmt from version 15. 23. 00.
