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

On this version, I have added the breakthreshold attr before Sim, but it still not working.

Maybe, it's not possible to control the breaking point per point…
