>>7958522See, part of it is that whoever sculpted this either had no idea what they were doing or were limited by material strengths. I've edited his right arm so that it's not so goddamn long(though I'm shit at editting), a double-joint only works if care is made when making it. Same as any other joint. However, each of these joints requires 5 parts, and given that the factories now charge per part, we'll never see this type of joint. Which is a shame, because the standard swivel/hinge joint(which requires 4 parts) can sometimes not even get a 90° bend to it
