Help Obi collision issue

[Henning]

Hi josemendez, 

Thanks so much for your reply! It was really detailed and educational!

Please let me rephrase my question. I originally said it was a crossbow just to simplify my problem.

In fact, I am using Unity to simulate a robot grasping a rope. The gripper fingers are very thin, and it moves fast. The grasp looks like below.



As you have suggeted, I first slowed down the movement of the fingers. However, even when at very slow speeds, the fingers could still push the particles away as shown below:

When I lift the gripper up, the rope just stayed where it was.

I also tried increasing the substeps, it did not show much effect as well. Meanwhile, the rope resolution was kept at 1 and in the thickness was set to 0.05. The Obi collider materials for both fingers were set to HighFriction/HighStaticFriction.

WIth your experience, do you think what I have been working on is viable? Thank you again for video and tutorial link, they are really helpful.
