Setting the stretching scale to 0.1 will tell the rope to try and keep their length at 10% of their rest length. Should be left to 1 (100%) unless you're going for some special effect.
If your ropes are sagging, either:
- Use more substeps (10-15 is completely fine). This will ensure ropes reach their target rest length during simulation. The manual contains an in-depth explanation of how iterations and substeps affect simulation quality: http://obi.virtualmethodstudio.com/manua...gence.html
- Decrease rope resolution. Less constraints will result in faster convergence and less spurious compliance (that is, less elastic ropes). A resolution of 0.6 means particles will slightly overlap each other, which means there's a lot of particles. Since your ropes are very long, that will require a rather high amount of substeps for the simulation to be accurate.
You can combine both: use lower-resolution ropes with more substeps.
Note you can use surface collisions in case your rope resolution needs to be low and gaps appear in-between particles.
kind regards,
