Weird normal map baking issues

as you can see in the picture.

i baked a normal map for hands

near UV boundary not according to there normal direction

Have you ever been experience before like this just gimme some advice for me

thank you.

It solved with baking onto original body mesh not only hands

still idk what’s different between two objects whole body and hand.

maybe because of material cause problems… i guess.

Or Overlapped Object. whatever, it’s not deep problem.
