Is it possible to use hook for group of vertices so the influence of the hook will have nice gradual effect like proportional editing has?
Thank for replay?
Yes, but it only allows one kind of interpolation.
Falloff
If not zero, the falloff is the distance where the influence of a hook goes to zero. It currently uses a smooth interpolation, comparable to the Proportional Editing Tools.
Thank you, I already knew this. BUt as you hinted this is not unfortunately enough
