Cool mate i hope you picked up a few bits from the tutorial. I cheated with the bullet sequence I used a soup attribute transfer node and a bounding box to toggle the nconstraints on the nCloth object to 0 as the bounded object passed through it. Then used a volume axis field to push the nCloth. It's a bit more complicated that that but that's about the gist of it.

Doing it that way lets me use 1 nCloth object and no passive coliders it speeds up the sim to about 50 fps with self collide turned on
