cluster q

hello all -

i'm working with clusters in xsi, setting up a simple eyelid animation where the top lid is defined by a cluster whose center is at the center of the eyeball. i have applied a weight map to the cluster so that the points taper off in their translation when the lid closes.

the problem is that the weight map that i have applied and painted for the cluster seems to have no effect when the lid is rotated.

the steps i used were...

tag vertices > create cluster >
make null and apply it as the cluster center >
select cluster and apply weight map >
paint weight map > rotate = nuttin

the weight map shows up in the the properties window for cluster... i'm allowed to even change its color... but the map has no effect.

any ideas?

thanks
