Vellum string that does not stretch


Recommended Posts


I have a simulation with a ball hanging from a string and I'm trying to achieve a string that does not stretch but can still bend, like a a bulb attached to an electrical cord.

I have set up a string constraint and maxed out the stretch stiffness and using 10 substeps + high number of constraint iterations but whatever I do the string stretches when the ball falls with gravity.


Appreciate any tips on how to make this.

if both string and ball are vellum geos it should work with reasonable amount of iterations

however vellum cant mutually interact with Bullet for example, so in that case it wouldnt work

alternatively you can go all bullet, and make your string out of softconstrained spheres with high stiffness and low angular stiffness
