Specifies the amount of squashing or stretching. Increasing negative values specify squashing along deformer’s local Y axis. Increasing positive values specify stretching along deformer’s local Y axis. Use the slider to select values from -10.0000 to 10.0000. Default is 0.0000 (no squashing or stretching).
See Advanced deformer options.
Specifies the placement of the deformer node in the deformable object’s history. For more information about deformer placement, see Deformation order.
Specifies the name of a new partition that will include the deformer set. The suggested partition name is deformPartition, which will be created if it does not already exist. Typically, you might put all your exclusive deformer sets in the partition named deformPartition. However, you can create as many partitions as you like, and name them whatever you want. Only available if Exclusive is on.
