Help  Make rope more stiff

Stiffer as in harder to bend, or harder to stretch? use bend constraints for the former, and distance constraints for the latter. Shape matching constraints are used exclusively for softbodies, as explained in the manual. They're not used by ropes at all.

Generally, you want to increase the amount of substeps in your ObiFixedUpdater used to allow for the simulation to reach higher stiffnesses (that is, lower compliances). Once you're happy with the overall behavior, you can tweak the amount of iterations used for specific constraint types. See the following page for an in-depth explanation of how the engine works internally and how substeps/iterations affect simulation quality: http://obi.virtualmethodstudio.com/manua...gence.html

At the end of that page you'll also find a list of all available constraints and the actors using each one.

let me know if you need further help,

kind regards


I may be doing this wrong, but I updated the substeps to 12 and saw no difference. I'm not sure if that's what I need. What I'm trying to do is make the rope look like the cable in this video. Where you can move the end and it will bend, but will mostly keep its shape.
