Help Obi Rod collision causing weird stretching behavior

[violinviolin19]

The main parameter that controls simulation quality and reachable stiffness is the amount of substeps. You can set this in the ObiSolver component.

The manual contains a detailed explanation of how the solver works internally and how substeps/timestep size affect the simulation:

kind regards,

Thanks, that's great! One last thing- I'm attempting to make a catheter that can bend at the tip via controller input (without an external force) and I'm struggling to get started with that. I have control points defining the top and bottom of the tip and I just want the particles there to bend into a candy cane shape and back without lengthening or affecting the rest of the catheter. Any tips?
