Brian Horgan shares one of his scripts for Maya, bh_JiggleConstraint which aids in creating automatic secondary motion to objects in Maya. Brian has created and shared many useful scripts in the past both for Maya and Cinema 4D, including his bhGhost Onion Skinning tool for Maya, and WalkCycleBuddy for creating walk cycles in Cinema 4D.
A short video showing how to use a tool I wrote for adding automatic secondary motion to objects in Maya
The bh_jiggleConstraint adds secondary motion to objects with a couple of clicks, and here Brian shows it’s use, and what the tool is actually doing inside of Maya. The bh_jiggleConstraint can be found on Brian’s Site Graphite9, or by clicking here: bh_jiggleConstraint for adding secondary motion in Maya
An important note that Brian makes regarding this script, is that bh_JiggleConstraint is provided “as is” and is not providing any support for it at all. Brain recommends to please save a new version of your file before using it just in case.
