你好，我想了解一下，我将同一个骨骼添加到多个皮肤后，再对此骨骼添加physics constraint。约束图标就会有个黄色感叹号提示。
我想知道这个提示是什么意思？目前看来不同皮肤physics constraint也能生效。但是需要什么样的操作才能使多个皮肤下的骨骼正确的添加physics constraint避免出现黄色感叹号提示。是否physics constraint也需要添加到不同皮肤？
关于4.2beta使用physics constraint后，皮肤骨骼的提示
If bones affected by a constraint are in a skin but the constraint is not, then you will get the warning. This is true for all types of constraints, not just physics constraints. This is because the constraint cannot be applied when the bone's skin is not active. To fix it, add the constraint to the same skin as the bones.
Also:
If your physics constraint has rotate, scaleX, or shearX > 0 and the bone length is 0, then you will get the warning. The physics constraint cannot apply those to a 0 length bone.
If your physics constraint has x, y, rotate, scaleX, and shearX all set to 0, then you will get the warning. This is because the physics constraint would do nothing.
In the near future we will add text to explain the warnings when they appear.
