hi,

 

yes, you're a bit dumb here ;-)

 

you have to create a cluster of each points you want to constrain an object to.

then use Constrain -> Object to Cluster, to constrain your the nulls to those clusters.

 

creating cluster with center means, that the created center/null will move the point.

 

 

here's a little script which will help you.

 

select the points you want to constrain to, run script, pick the object.

 

the script will duplicate the picked object and constrain it to each selected point.

(if you select the target object in object-mode it will constrain to all points.)

 

cheers,

 

Juan

Hi,

 

This seems pretty straightforward on the surface but I can't get it to work. I rarely use cloth (XSI or Syflex) so please bear with me J

 

I'm trying to constrain some nulls to an animated (XSI cloth sim) flag; one per vert. For argument's sake, shape animating the flag is out of the question J

 

If I mute the cloth sim and create a 'cluster with center' for each vert, when I move each resultant cluster centre null, the vert follows as expected...the vert is constrained to this null, however I need the opposite of this; I need a null constrained to each vert. So I think if I constrain another null to each cluster centre, all will be well; nulls will follow nulls.

 

However as soon as I unmute the sim, the cluster centres don't follow their respective clusters on the cloth, so there's no point in further constraining anything to these; it's as if the cloth sim ignores/overrides any constraints.

 

Am I being dumb here? What's the best way to constrain anything to the verts of sim animated object? Is it possible?

 

TIA,

 

Jeff.
