As the title says, i need a bit of help. I recently got into modeling and im facing my first MAJOR problem today. I started off with a little bit of frankensteining. Problem is that after replacing the arms of my model, the placement is a little bit off. I have tried using a "MultiEdit" addon but that messes everything up, tried using ctr+j to merge the meshes and then split but that screws everything up. So my question is, how do you connect vertices of 2 different meshes without screwing up parenting/other stuff?
