LOL.

Mr Gimble visits my animation clinic daily...then he just runs away.

Hey,
I just got into using gimbal rotations after using local, and I aint never going back.
All the keys I set actually work now.

hi,

gimbal rotate tool, so i can see where the gimbal lock is.


if you use local rotation, you`ll need to use the euler filter in the graph editor to fix some weird rotations

on the offhand I use local and some gimble occurs...I have created a small button to help me filter the curves...

make this a shelf button or hotkey or add it to a marking menu:



// EULER: THE FUGITIVE

// CATCH DR GIMBLE!!!

// list animCurves in scene
string $drGimble[] = `ls -typ animCurve`;
// EULER filter on curves
filterCurve $drGimble;



that will filter all anim curves in your scene...no more having to select them by hand and go through the Graph menus...

simple but effective...

You need to be more specific with that script. Listing all animCurves will include driven keys, when you want the animCurveTA.

I haven't used the filter curve function (as I just stuck with the gimbal tool), but have heard that mocap people write their own filter because the Maya's one does not work as it should. Also, what does filterCurve do to tangent handles?

ragtag:

yes. you could use animcurveTA...thanks for pointing that out :)
[though I have never seen the filterCurve command adversely affect non-rotation curves - I took it for granted that it only affected rotational curves, so listing the animCurveTA seemed superfluous] :)

EDIT: this was clipped straight from the docs - "The Euler filter demangles discontinous rotation anim curves into smooth curves."

I mainly use the filterCurve function when I have a skeletal file from my game engine imported into Maya. when I transfer animation onto my IK rig, I try and loose any gimbal issues then with that script... in my experience, Maya's filter works fine, I have never had a problem with it... :)

That's pretty slick.
