Is it possible to export hand animation with translation without breaking breaking fingers?

[ayamashi]

I'm trying to make a hand finger movement animation that also uses attachment point movement but need to check with translation on avastar export for the attachment.

I set the finger movement only as rotation keyframes but it still breaks fingers on kemono. On maitreya or ebody it looks kind of OK, but kemono really distorts the hand so I feel like I'm doing something wrong.

Is there any way to prevent hand finger deformation ?

Thank you!

Generally exporting joint positions along with rotations is a recipe for trouble.

The most reliable way to use joint positions without causing unintended breakage is to export to the .anim format, one without joint positions, one with joint positions. Then, using a tool called AnimHacker, merge the joint positions for the joint-of-interest into the rotations-only version of the .anim. That way, you should not see any (unintended) breakage.
