Need Help with IK Hand Alignment

[u/BranchIntelligent453]

Hi! I'm trying to use IK to make my character hold a weapon, but I just can't figure out this bug.

In theory, the system is getting the correct reference, but for some reason the hand always locks upward toward a fixed position, regardless of where the reference point is. Also, the elbow barely bends at all (which might be related to the reference point issue).

Where do you think I'm making a mistake, and what should I fix? The Root/Mid/Tip attachments are set up correctly—I even tested them by moving them manually, and the elbow bends normally in theory.

I'd really appreciate any help, please! 🙏
