[Bf-committers] New WeightVGroup Modifier

[Tobias Oelgarte]

As far as i could see and read it uses the distance to the origin of the 
target. Which is pretty fine for your Dynamic Subsurf task. But for only 
mesh weights, i would really appreciate if it could use the (shortest) 
distance to another mesh. That would give this modifier a whole lot more 
possible usages. (Something similar to bone heat weights)

Just for curiosity: Does it change the weights of the affected group 
permanent or on the fly?
