Hello,
I’m not sure why, but I don’t tend to share a lot of what I do with the community, but I read the maxObjectTab tutorial on Paul Neale’s website and got some extra help with the same subject on here so I decided I’d share two scripts that I quickly created.

The animatable pivot script is a strange one, it works perfectly well without Auto Key enabled but messes up with it on, but I thought it might be a good starting point for someone to do further development (I know Felix Joleanes has an animatable pivot plug-in but, hey, it’s fun trying to write your own stuff). It’s based on Jason Schleifer, use the cross helper to get the location of where you want the pivot to be and then “Snap Pivot to Move” button to actually reposition the pivot
Hopefully they’ll be of use to someone.

Hey Harry,
Thanks for posting this stuff up. I learn a lot from this kind of thing.
On the animated pivot, there was a post in the rigging section a while back. A guy was trying to replicate this Maya tutorial in Max but couldn’t since Max’s animatable (CAT) pivot, in my experience anyway, doesn’t work very well.

I see you’re using the CAT pivot and wonder if the Autokey on/off problems you’re having are just bugs with the CAT controller or something else?
Would the rolling pivot in these tutorials (below) even be possible using the CAT pivot? Would this be possible in Max at all? Or is this just another area exclusive to Maya?
