I'm creating a character for a new game I'm developing and the character is supposed to be very round with plump arms and legs. When i tried to boolean union the round head with the round body it became jagged. I think it's because of the vertices and their connections but I even if I'm right I don't know what to do about it. Any suggestions and is it something that can be solved by sculpting, modeling, or both?
The goal is to have the character rigged and animated so just having a temporary visual modifier isn't what I'm going for. I just want the head to rest on the body but still be able to move it around when I rig it.
I also need to add arms and legs to the main body mesh too.
I put the blender file here in case anyone wants to take a look.
