Here is a swarm of worm I did using Vellum.
It was made for a short 3 week project. You can see it here : https://vimeo.com/groups/ati/videos/313561748
I hope you’ll like it.
As you can see, there is still some problems with the collisions, and it is not perfect, but i’m quite happy with the overall aspect.
