How to get rid of these shadow spots ?

Anyone got a clue what’s the problem of mah assets ?
i dont know anymore.

If i put Ambient Occlusion off, then shadows are gone, but i think it’s wrong kind of fix o_O

Help plz i dont know nothing anymore

I think that it is most likely caused by ambient occlusion texture? Could you check the materail to see if there is nearly-zero value in ambient Occlusion texture if your material uses that.
