animating envelope in blend shape via ramp
i made a plane, duplicated and modified it. applied a blend shape.
now the tricky part.
i want the envelope be animated so that the blending does not occur everywhere. only where the ramp says "hey Mr.Plane please deform here, yeah right here where I tell you envelope is 1" or sth like that.
is this possible??? i applied a a ramp, projected it... but nothing. there is only something like an on off switch but i couldn't blend the way up the plane.
so, is there a way or do I have to model all the steps in between???
thx in advance,
