EDIT: Added file(s) for Houdini 18.5

How do you trigger a specific behaviour in Vellum using another attribute?

In this tutorial we'll have a look at two ways of triggering the inflation of specific areas in a softbody simulation using a bit of VEX and the falloff nodes from MOPs.

You can download MOPs for free here:  https://www.motionoperators.com/

Hey guys! I can't achieve this effect following the tutorial in houdini 18.5, the geo doesn't return to its orginal shape after the falloff. I've been playing with the parameters and slightly raising the factor that multiplies the restlenght(to 0.3) it re-inflates a little, but is still wrinkled. What should I touch to make it work in H18.5 or maybe is this setup obsolete for version 18.5? Thanks

Hi Dani, I just checked and rebuilt (and uploaded) the file in H18.5 - although there's not really any difference I can point out... Nevertheless - hope its helpful. Cheers, Mo

@Entagma Hello Mo! Genius - Can you show / tell us how we can "set initial state" for our sims? For example, can we have the sim in the initial state at frame 0? Thanks!
