How to animate a cloth tear with split verticies?

Hello, so I was looking at how to do basic cloth ripping physics sims, which seems simple enough, but I was wondering how I can delay the tear. This is tricky since from the tutorials I’ve seen, you use the knife tool and then put those vertices into a vertex group that you then split. But then the cloth rips at those points as soon as you start the simulation. How can you have the vertices act as if they weren’t split until the cloth interacts with another object?

I’m looking for something similar to this effect… but I want it to be slower. Like a person tearing apart a cloth with both hands so it’s not instantaneous.

I think it’s possible to slow down the animation of cutting and reduce gravity or give it to gravity.

Do you want me to move slowly after cutting?

Wouldn’t it be possible to convert it into a shape key and animate it.

It’s just an idea. I didn’t actually make it :sweat_smile:

I could slow the animation down, but what if I want to animate the cloth as being in tact at first and then torn?

Haven’t you tried the method of the video attached above? :hushed:
In the video, the fabric is cut using Boolean modifiers.
The timing and speed at which the fabric is cut are determined by the object cutting the fabric. :thinking:

Like this old tutorial ? Maybe some idea can be transfered to the newer blender version ??

…or this (a little bit newer :wink: )
