i'm not very savvy with roto but i imagine one would have to
solve some fundamental problems which are quite tricky.. for instance:
what would happen to the falloff behavior *between* control
points? assuming the falloff gets generated by mathematical
formulas, lets say point A has a linear falloff and point B has
a power function. now we look at a non-control point point C
somewhere between A and B (cue hitchhikers guide reference ;),
what formula would you apply there? to get a smooth transition
from A to B we'd need to dynamically change formula A to formula
B. i guess you could try a dissolve between the two but i
imagine the math gets rather complex and in worst case that
would result in some kind of double edge.
just some thoughts

Thanks much for your reply.
- dragging out the feather control points would only change the
DISTANCE of the Feather Falloff at each point, but i need to
change the COLOR or Grey Shade at EACH control\feather point,
which is what the Feather Falloff Value lightens or darkens but
only for the Entire SHAPE or ROTO.
Any ideas\suggestions appreciated,
Jeff
