How to use Tearing correctly

[RickYang1]

I want to use Tearing to achieve the eyeball capsule membrane tearing. I tested the scene of SofaUnity24_06: Demo_02/TearingInteraction, but it's difficult to achieve a similar performance like this， The performance I tested is as follows:

In my testing, a lot of debris is generated and it is difficult to tear out a continuous path. When I keep dragging a triangle, the performance will be worse(at the 17th second). Why is this? What can I do to optimize it？
Thanks in advance!

Hi,

yes we know that the Tearing behavior is not stable. We are working on it but lack of time/resources to improve it.
You can try to modify the fractureMaxLength (bigger value will create larger incision each time) and the stressThreshold (higher value will create incision only when you stretch more) here:
in the .scn file

Thanks for your reply again. I will test the methods you provided.
Best regards!
