Limit Rotation Constraint 限定旋转约束


值得注意的是,尽管约束限制了其视觉和渲染旋转量,约束对象的数据块仍然允许(默认)对象或骨骼的旋转量超出最小和最大值确定的范围,其旋转量可以在 变换 面板中看到。当旋转物体,并试图超出限定边界,视觉上以及渲染时,物体仍然被限定在边界内,但在内部,其旋转量仍会变化为超出限制。如果约束被移除,约束对象将跳转到其内部指定的旋转量。

类似地,如果约束对象的内部旋转超出范围,把它旋转回到限制区域,在其内部旋转回到限定阈值范围内之前,看上去会像是什么都没发生(除非你启用了下文提到的 针对形变 选项)。

为某个轴向设置相等的最小值和最大值,可以锁定约束对象绕该轴向的旋转... 尽管这样是可以的,但使用 变换属性 的轴向锁定功能可能更简单。

如果骨骼是由IK解算的,该变换无法约束骨骼。约束用于IK的骨骼的旋转,请参考骨骼属性的“反向运动学Inverse Kinematics”章节。



Limit Rotation panel.

X, Y, Z 最大值/最小值

These buttons enable the rotation limit around respectively the X, Y and Z axes of the owner, in the chosen Owner Space. The Min and Max number fields to their right control the value of their lower and upper boundaries, respectively.


  • 如果最小值高于其对应的最大值,则约束的行为就像它具有与最大值相同的值。

  • 不同于 限定位置约束 ,此约束不能单独启用下限或上限…

Affect Transform

As pointed out before by default, even though visually constrained, the owner can still have rotations out of bounds (as shown by the Transform panel). When you enable this checkbox, this is no more possible -- the owner transform properties are also limited by the constraint. However note that, the constraint does not directly modifies the rotation values: you have to rotate one way or the other its owner, for this to take effect...

Owner Space

This constraint allows you to choose in which space evaluate its owner's transform properties. See common constraint properties for more information.


Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.
