Research direction

Start with SeparateJointModelTransform.java at the referenced inverseModelBindMatrix line and review the saveBindPose() path described in the issue. Reproduce repeated saveBindPose() calls and trace whether the inverseModelBindMatrix is modified; done means repeated calls no longer corrupt or distort the model's bind pose.

Description

bug

As reported here: https://hub.jmonkeyengine.org/t/issue-calling-armature-savebindpose/48046

Essentially, calling saveBindPose() many times will eventually corrupt/distort the model's bind pose.

My best guess so far is that the inverseModelBindMatrix value in this class at this line ends up corrupted from repeatedly being modified one way or another: SeparateJointModelTransform.java#L33
