Removed auto-fill body bone mappings log.
Fixed various solver issues (leg, arm, hand) including automatic bone mapping assignments and exposure to blueprints.
Fixed crash issues related to incompatible skeleton mappings and improved error message readability.
Fixed some issues with arms appearing stretched when space is scaled down and potential issues with leg scaling.
Error Handling and Validation
Added error handling for pose generation issues, notifying users when wrist bones cannot be found due to incorrect hand bone mappings.
Enhanced error messages in the tracking step to notify users when no tracking class is selected.
Improved license validation error messages and deactivation options for maxed-out machines.
Crouching and Tilting Pelvis: Crouching and tilting the pelvis may not work properly unless the pelvis bone's forward axis points in the direction of the spine.
Hand Solver Poses and Debug Categories: Hand solver poses and debug categories might not be ordered correctly.
Hand Solver Reference Poses: The hand solver may not throw errors when reference poses are missing, potentially causing runtime crashes.
Tracker Mappings Error Messages: Tracker mappings can stack error messages in the viewport, making them unreadable.
Typos and Error Messages: Some typos and error messages when pose generation cannot find wrist bones due to wrongly set up hand bone mappings.
