When you use skinning with one or more deformers to deform an object, the final effect of the deformations can vary depending on the order in which the deformations occur. By default, the deformations occur in the order that skin was bound and the deformers were created. The skinning or deformer algorithm node created first deforms the object first, and the algorithm node created last deforms the object last. However, you can change the deformation order to get the effect you want.
To change the deformation order for a skinned object
-click the object being deformed and select Inputs > All Inputs from the marking menu.
-drag the names of the skinning or deformer nodes in the list to place them in the deformation order you want.
