Re: WeightMap on a lattice

Or you can pick directly the lattice for the cage deform :-).

Hi Joe,

You could try building a polymesh cage to use to deform your object
instead of a lattice (you could even just build a lattice out of
polies if you wanted it the same). Then you can control the shape
jitter with a weight map.

I've no idea if you can put a weightmap on a lattice or not, so I'll
assume not seeing you've asked the question ;-)

Cheers,

Alan.
