Vellum Constraint - Can we Destroy them with an attribute into a Vellum solver ?

[Zhaie]

Hi here so my subject is : Inflate and Pop a geometry ( Like the pig head) 

I'm feeding a remeshed pieg head with Pieces generated with a edge fracture into a Vellum cloth. Then i add a Vellum Weld and a Vellum pressure to sew the pieces and inflate the Pighead.
Inside the Vellum solver i animate the Rest Lenght Scale to inflate the balloon. 

Now i'm trying to break it : 
I start playing with the Breaking Thresholod in the VellumWeld : i try different values but i'm not achieving what i want.

So i create a vellumconstraintproperty  in Vellum Solver and animate with Breaking Thresholod  value. it's stay at -1. so it's not working at all.

I told myself, i could animate a map or a group ( Like with RBD)  and destroy the constraint inside the vellum solver. that would give me a lot of control but that's not working either ( or i dont manage to build something )

And i a saw some Entagma's Video and this but i'm wondering if i could have more control on that

 

Any idear ? 

Have Nice day all !

If you want full control of when constraints break you can use the vellum constraint property node and either hand animate or drive by an attribute the "broken" and if you want also the "remove" parameters. If a vellum constraint has a broken value of 1 it will immediately become broken and stop constraining things in the sim.

Slightly less procedural but it gives you the maximum amount of control possible.

Hope that can be of help!

thanks a lot for your help @underscoreus  it helped !
Since i get more confident with my knowledge on vellum. Now i'm playing with the Vellum constrain properties a lot in both DOP and VellumSolver. Using Vex or only Hscript in it  it was really hard to understand that some properties are more on the geo ( like Weld) or in constraints. Also it was not clear for me that the constraint created are not updatinng onn SOP but you can update them into solver.

Anyway the Advanced vellum video helped a lot if someone want to understand vellum it's a must
