Help Understanding This

Nowadays, TyFlow have few methods of dealing with concave shapes, but in the first releases there were only convex collisions, so workaround was to brake concave shape to smaller parts with voronoi, link them all together, and then it would work fine. 

Hope this clarifies a bit.

Yes it does, as it was an older scene I was refering to and it was doing exactly that.
