graph editor/driven key problem

Complex UV Layout in Maya

Over the last couple of years UV layout in Maya has changed for the better. In this course we're going to be taking a look at some of those changes as we UV map an entire character

i've made attributes for a model, with driven keys for certain actions like punching, etc. i noticed though that sometimes when i rotate the left arm, that it freaks out between keys, because it's going from a Z rotation of 300 to -30 for example, so it rotates the wrong way. i opened the graph editor to manually fix it, but i realized that by using driven keys, that the rotation etc. of the arm isn't shown. i see a black line which represents the driven key, and that's it.

so how can i use the graph editor if i'm using driven keys? i could just key each frame until it's alright, but it's going to get annoying if it keeps happening...

,

are you using IK chains?

if so, i feel your pain :hug:

I'm forever tweaking the tangent of these IK chains on animation..so like if i have a key set for motion, i tweak the chain on each key if it calls for it.
i figure it's to do with the negative value crosses it's 'plane' of reference so the chain flips.
