Working on my model's arm/shoulder setup, figured how to have both inverse and direct kinematics with a simple change.我的模型工作的手臂/肩膀设置，想出如何使一个简单的变化都直接逆运动学。 These are two different ways to control character's limbs so they either follow the hand or the movement is directed by the shoulder (In the case of the arms).这是两种不同的方法来控制人物的手脚，使他们要么跟上手或肩膀的运动是由（在武器的情况下）执导。 It's important to be able to use both kinds because some movements look wrong when using the wrong kind of kinematics, and since I suck at rigging I've mostly been muddling along with inverse重要的是要能够使用这两种看上去有问题，因为一些动作时，使用的是一种错误的运动，因为我吸在操纵我大多被得过且过与沿逆 
The problem is whenever I upgrade my character rigs it runs the risk of making my older animations no longer compatible (Some old ones I can't even open without crashing the 3d program!) so instead of building an ever increasing library of movements it's all a bit of a mess.问题是，每当我升级我的性格钻机运行它使我的老动画的风险，因此不再兼容，而不是建立一个不断增加的动作库中的所有（有些我什至不能没有崩溃的3D程序！打开旧的）一有点乱。
Dunno if anyone cares about this kind of technical detail on a porn site but there you go不知道如果有人关心这类技术细节上的色情网站，但你去那里
