Hello! I am modelling a character that is going to have multiple bones. Alright. So I know that how bones work in blender. You basically have a joint between two spheres and this structure forms up a single bone. Then the bones' spherical parts act as the joints. But now I am confused that should I use a single whole bone to point movement of a certain part of the character and keep the bones connections like that every sphere is connected to each other between multiple bones or should I make the connections so that every entire bone is at the center of the part i want to assign the bone to and connect the bones to each other with these dashed lines. I am asking this because I have seen that every model that has been decompiled have bones connected to each other with those dashed line instead of being connected with each other from the spheres. Can someone help?

Thanks.
