About

The Force Modifier acts like a combination of hooks and proportional edit.

Vertices that fall within the sphere-of-influence around the control object, are affected by the appropriate proportional-edit falloff chosen.

The vertices to influence are determined from the position of the verts before this modifier is applied at current point.

Vertices can be pulled towards or pushed away from the target object. How exactly the 'pushed away' will be done still has to be determined.

The advantage of this over hooks or proportional edit, is you don't have a fixed region of influence. You can have influence over various areas too. May be good faking oceans or certain cases of cloth behaviour.

Current Status

Well, I'm currently learning the modifier code. I have to say that it is fairly cryptic, although there are some aspects of it that are actually quite neat.

EDIT: now I've gotten this working after 1 day of coding. I'll submit a patch sometime. Patch #5064
