Hi, I have some issues with Vellum Hair. 
	With the Attach to Geometry constraint I can't found with wich attribut vellum activates the breaking. 
	 
	I would like to break my constraint when my points turn red. I don't want to deactivate the constraint on each point simultanitly. 
	I have try to use a Vex Expression in the Vellum Constraint Property but I can't control the Breakthreshold attribut per points. 
	 
	Do you know any way to do this ? 
	 
	Thanks
