I'm currently working on a rope macro that will generate a rope along a
spline.
The output is a mesh2 with a uv_map.
I'll make the macro available when it's finished.

Mike,
Best I've seen so far.
Rope technicalities - attention to detail.
A cabled rope is typically a 3-start helical bundle. And typically
right-handed.
A nice example is at
http://www.bestdock.com/pics/extras/Rope.JPG
Your rope looks like it has about 6 strands and is left-handed.
Also in the first bend (from the left) it appears to be unravelling (strands
are more parallel with main axis).
Keep up the good work.

This particular example has five strands, but the macro allows any
number not less than three.
The macro supports left handed rope by setting a negative value to the
Twistiness parameter.
I don't think it actually unravels, it's just an illusion caused by the
perspective.

As always, great, Mike, and thanks. I learn more from your tutorials, and
examining your examples and macros, than about any other way.

I'd love to see an example of a three-strand rope with a left hand twist
to it .. there was something about this one that just didn't feel quite
right.
Then:
... your next mission, should you choose to accept it, is to create a
macro for a stranded 3-strand rope. Not sure of the specs, but each
strand in hemp ropes tends to be a twist of smaller strands ...
Cheers!
Rick

Exactly! Would have said the same! Great work Mike!

Why not directly implement a fractal rope, each smaller strand being a
twist of smaller strands being ... ? ;-)
