For male characters, when only FK is enabled and the green light (enabled/activated) for body is turned on in the FK section, the Rotation function for the bone cm_J_dan_f_top in KKPE becomes completely unresponsive/invalidated. Only the Position function still works. This results in a strange state where only Position is effective while Rotation is permanently disabled.
Even if you try to set keyframes for Rotation using the Timeline, they have no effect — the Rotation remains invalid and unresponsive. The Reset Rotation button for cm_J_dan_f_top in KKPE also does nothing (fails to reset).
The issue resolves normally if you either:
Turn off the green light for body in FK, or
Switch to IK mode.
Female characters do not have this bug — cm_J_dan_f_top works correctly for both FK and IK states.
However, if you change a female character into a male character.then save the scene card and reload it, this bug will appear and become permanently embedded in the scene card.
Even if you later switch the character back to a female body, the bug persists and cannot be fixed. The only way to resolve it is to completely delete the character and re-import/load a fresh one.
When only FK is enabled for a male character, turning on the green light for the body causes the 【Rotation】 function of the cm_J_dan_f_top bone in KKPE to become ineffective, leaving only the 【Position】 function working. As a result, it enters a strange state where only 【Position】 works and 【Rotation】 fails. Even if keyframes are set for 【Rotation】 in the 【Timeline】, they cannot take effect, and the failure persists. The 【Reset Rotation】 button for cm_J_dan_f_top in KKPE also becomes ineffective. Turning off the green light for the body in FK or enabling IK restores normal functionality.
Female characters do not have this bug; cm_J_dan_f_top works normally in both FK and IK states.
However, when replacing a female character with a male character, saving the scene card, and then reloading it, this bug occurs and becomes permanently embedded in the scene card. Even switching back to a female character cannot restore functionality. The only solution is to delete the character and re-import it.
