I tested some ideas for tearing cloth using the weld modifier before cloth.
Basically I set the cut manually separating the plane in two mesh islands in the same object and welded them with weld modifier. After that, I used the cloth solver. It begins well with the welded mesh but when I disable the weld modifier seems like the cloth resets the base mesh from that moment and continues the simulation badly(from my point of view).
Someone can please help to understand if it’s a BUG or a design issue?
