Hello. Im trying to set up a simulation where cloth will hit a pyramid and tear. I've set the pyramid as a static body object and a plane above the pyramid as a cloth object.

When I run the simulation the plane falls on the pyramid like a cloth but I'm wondering how I can get the cloth to tear. In the help it said I need to get the stiffness, bend, and shear over 10% of the tear threshold which I have but still no tearing. I added the tear cloth modifier but that didn't help.

Hi,

First of all, welcome to the forum!

I highly recommend going through the Masterclass: Crumpling and Tearing [sidefx.com] for cloth to understand more about how cloth is implemented in Houdini.

Have fun!

Cheers!

Make sure that you switch on “Enable Tearing” on the cloth solver when you want to try out tearing. When starting out with a default cloth object, you probably want to start by try smaller tear thresholds, for example 0.05 for the stretch tear threshold.
