Driven Keys: On or Off switch?

[bobafet]

Maya that should be fairly simple, but I can't find a way to do it. (maybe it needs a workaround and it's not as simple as I might think)

With a Driven Key, is there a way to turn the influence of the Driver object on or off? Sort of like a Constraint where you can keyframe the weight, but I'd like to have an object animated by the driver to a certain frame, and then have it be manually keyframed after a certain frame.

Can this be done in a fairly simple way? I'm pretty sure that you could do it with an expression, but alas I'm not very capable in this respect yet (just learning). Are there any MEL scripts here on HighEnd3D that can do this? Any suggestions will be greatly appreciated!

One way... make 2 dummy atributes. Then make a switch atribute. Let the drivven key dirve the other and let you manualy drive the other. then use an expression (simlple if else clause) that lets the other value be connected to the real one when switch is on and other when off.

To make things a bit easier make a mel script that swiches the switch and makes a automatic key for the manual anim curve (so that no visible pop occurs). This just so you dont need to manualy do this.
