Add Pinning Groups

This is a utility for mesh hair. When doing cloth simulations we often want part of the mesh not to move, whereas other parts should move more or less. The extent to which a certain vertex is pinned down is controlled by a vertex group.

Select the hair mesh (the scalp should already be separated as another object) with the default settings, and press Add Pinning Group. This opens a curve which determines the weight assignment along the strands.

A new vertex group called HairPinning is created. The weight assignments can be seen in Weight Paint mode.

If the default weight assignment was not satisfactory, we press Add Pinning Group again. The HairPin group is now updated with new weights.
