how to minimize rope distortion bungee jumper

Post by starfish30 »

The image on the left is the original. The rope is on a separate layer and has a lot of bones. I'm using gravity and pivot on origin for the animation but as you can see it doesn't look very natural. Is there a way to get a better result? Should I chop the rope up into smaller pieces? Thanks!

So you're using dynamics? Interesting.

I would recreate the rope art and make it a straight line. Then I would rig it using Sketch Bones. This would give me a bones setup that deforms into almost any shape nicely. IMO, rigging a rope in an irregular rest shape can't be animated predictably or with smooth segments, even less so with dynamics.

BTW, I'm not sure how I would animate that with dynamics, never tried it for dangling rope. (Not inside Moho anyway.)

You can also use Follow Path to deform a rope image but I don't think you can use dynamics with that. In some ways, that could be easier to animate. It depends on the motion you're going for.

Either way, I'd animate the rope manually in Moho but that's probably just me.

Ok, now I'm intrigued and I might have to give it a shot with dynamics tonight. :)

Thanks for the advice. I want the rope to initially look like it does in the original image. I'll try and straighten it with puppet warp in Photoshop, then bend it back in Moho and see how that works.

I've done something similar before with physics but it was less complicated.

I'm mostly using Moho to animate images rather than making cartoons. It's lots of fun to add realistic motion to static images.
