PRB: When Points in an Envelope Move with the Wrong Joint

SYMPTOMS

When you create envelopes that are weighted relative to a joint, certain points in the envelope might move as if they are weighted 100% to the wrong joint. If this happens, you might have to modify the weight of the joint to ensure that all the points of the envelope correspond with the correct joint.

RESOLUTION

If a particular envelope is behaving strangely, set the 'Skin -> Deformation Parameters -> Joint Area' value to 0.0. All points in the envelope should now follow their assigned joint.

MORE INFORMATION

The Skin -> Deformation Parameters -> Joint Area command allows you to control the percentage of the envelope that is affected by rounding as the joint bends. On the envelope, every point whose projection falls within this region of the joint receives a rounding effect. The rounding is most useful for tube-like envelopes that are assigned with the Full Weight option.
