Lattice, Cage, Curve (The weight maps in curve are only for translation, 
not for controlling the amount of curve.), and Bend all lack the ability 
to modulate their effects with a weight map (as far as I can tell).

Right now I am really wishing Lattice had this ability. As I have bean 
able to make the world-space fractal noise I was asking about by applying 
a randomize to a lattice and moving the lattice in 3D space. I am having 
to settle with using the falloff from the lattice cage instead of using 
the weightmap like I would prefer.

Imagine the tool I speak of, though... I assume it would have to record 
the base state somehow (perhaps you make a duplicate of the object and use 
that duplicate as a morph target, but this duplication would be less than 
ideal). Essentially the tool would let you blend in another shape through 
a weight map (with the option right there to invert the weightmap).

I wonder if there is some way to do this with Shape animation now. I have 
not gotten into shapes et, but my quick fiddling and skimmng of the docs 
did not turn anything up.

I am always open to alternate solutions / cheats, though. That is what 
this business is all about ;-)

Thanks,
