View Full Version : Rigging a Lasso

What would be the best way to rig a lasso? I am having a hard time to rig one that is easy to animate.

SplineIK with softbodies would be one way of doing it. You can get some pretty different behaviours/styles out of it by adjusting weights on the particles and adjusting attributes on springs. We wrote a script here that we mapped to a shelf button(or hotkeyable) and that switches the IK/Dynamic curveshape node worldspace[0] -> in curve connection for the IKH so you can pose it and then switch it to dynamic after all is said and done. You can pose it without doing that but you won't see the geo move until you hit interactive playback. It's really easy to setup and alot of fun to use.

Create splineIK normally, add some clusters and controls, select the IKH curve and make softbody. Make copy dyn and original a goal of 1. Then select the particles and add springs. Then you can go in and individually weight the particles. Then to get the joints to follow the softbodied curve, open up the connection editor, reload the left with the dynamic curve SHAPE node and reload the right with the IKH and connect the worldspace[0] to the In Curve and voila. You can switch back and forth that way or you can script something up pretty quickly so you can hotkey the switch. Once you've got the IK using the dyn curve then hit interactive playback or make a playblast and you'll see it in action.
