Dynamic COG in rigs


#1

Hi,

I’ve been asked in my production for a dynamic Center of gtavity as shown in in this rig at 2:28 th sec.

Does anyone know how to add that functionality. I would be highly helpful.

Thanks in advance

“Dynamic” isn’t really a good word to use in this case. You’ll find a bunch of tutorials for dynamics.

What you can google is “maya animate pivot point” and you should find some tutorials.

The related attributes you can start to play with are:

.rotatePivotX
.rotatePivotY
.rotatePivotZ
.rotatePivotTranslateX
.rotatePivotTranslateY
.rotatePivotTranslateZ
.rotateAxisX
.rotateAxisY
.rotateAxisZ

Thanks @chrislesage

I will look into it.

Here you can see two simple extra alternatives for this. One is using a constraint with an inverse matrix and the other just a simple multiply divide…

Thanks @Jerome

That’s exactly what I need.
