Changing Obi Rope Particle Size

[josemendez]

Sorry, I wasn't really explained my problem in the previous message. 

In the screenshot, if I pull the rope a little bit more it pass througt the obstacle. It was not like this when the particle sizes are small. Should I need to create a longer rope to solve this issue?

The issue here is that the collider is now smaller compared to the particle size than it was before, so it is easier for it to slip trough gaps in between particles.

Either use a smaller timestep (or more substeps, which is equivalent), or use more contact/distance iterations.
