Hi,

I'm fiddling with tearing cloth and from my understanding it was not supposed to allow single polys being completely tore, only groups of polys. Nevertheless reality shows the opposite… Is there a way to avoid that?

Cheers

you can create tearthreshold float attribute on your geometry which will be picked up by cloth object and probably multiplied with its Tear Threshold parameter
it is as well created when you click paint tearable from shelf
so just instead of painting it with Paint Sop you can vary that attribute in any way, noises, texture, whatever

similarly you can use enable tearing attribute
