>>59155723There's a couple problems I run into. I could make an addition to cover the back of the ball joint and layer it onto the upper leg like the muscles in a real leg would, which would give it more of a rounded butt look, but if the leg bends backward the deformation would probably look a little strange, and then it also brings up the question of "if there's synthetic skin material for the butt, why wouldn't that same material be used to cover the entire body and cover all the joints?" I could do it the typical BJD way and have the top of the upper leg be the joint itself and sculpt it to look more cheeky, but then it starts to look more like a doll and less like a machine. I can sculpt the pelvis area to have a more defined butt shape but that would limit the range of movement that the hip joint could achieve. I mean, ultimately it wouldn't matter because it's going to be a 3D model and I can just have the leg clip through the pelvis, but I'm a stickler and want it the body's construction to make sense on some level; I don't want to restrict the movement of the limbs too much.
Trying to make the joints work in a believable way while also making them have full range of movement AND be aesthetically pleasing is rather difficult.
