Hi
Is it possible to stop a rope from twisting at its attachment point? Using Rope extruded Renderer.
I would like the end control points to be clamped in place with no rotation.
Perhaps I'm doing something wrong?
Cheers!

Ropes do not model twist/torsion, as explained in the manual:

If you mean
bending, using ropes you can just attach two control points that are very close to each other. This works because a single point in space does not determine a direction, however
two points do.

This "offsetting" is just the rope rotating around its longitudinal axis. This kind of rotation is called "
torsion", and ropes do not explicitly model it: they're free to rotate around this axis.
Rods on the other hand use a much more accurate model that considers coupled torsion, bending, stretching and shearing (compared to rope's bending and stretching only), allowing them to reproduce a range of complex behavior that ropes cannot (plectoneme, coiling, etc).

Ropes can be torn/resized, but can't model torsion. Rods can model torsion, but cannot get torn or resize (see the comparison chart here:
http://obi.virtualmethodstudio.com/manua...setup.html)
So if you need both you're out of luck
. You'll need to bake the rod's mesh and then slice it using some other means.
