Help Make rope more stiff

[josemendez]

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.

The behavior shown in the video has nothing to do with stiffness and it's unaffected by substeps, it's called plasticity:

The opposite of stiff is compliant: stiff materials are hard to deform, compliant materials are easy to deform.
The opposite of plastic is elastic: plastic materials keep their current shape when deformed, elastic materials return to its rest shape - regardless of how easy or difficult it was to deform them in the first place.

A spring is an example of an elastic object: there's both stiff springs -like the suspension on a car- and compliant springs like the ones in ballpoint pens. Both will return to their original shape when you stop deforming them.
Copper cable is an example of a plastic object: there's stiff cable that you'd have a hard time deforming with your bare hands, and compliant cable that's easy to deform. Once deformed, both will keep the shape they're deformed into.

Some materials transition from elastic to plastic behavior when deformation exceeds a threshold, this threshold is typically called the yield threshold. Think of a spring that you've stretched way too much, and it does no longer return to its rest state: part of the deformation becomes permanent.

You can set plasticity parameters on bend/twist constraints, which are used by rods instead of ropes. See:
