Set Driven Keys Example?

[mzartler]

Hi All,

I'm trying to use set driven keys to pass the keys from one object to another. Animate 1 object based on the keys in another. I can't seem to get it to work.

My small example, just a 4 torus blend shape, The blend is named "Mouths".

My controller object, for this test, is just a text box with custom attributes, OPEN,MID,CLOSED with keys associated with the custom attributes.

I can animate the Mouths' blend in Channels, or in Blend Panel.

Set Driven Key...
I select the blend name/target in the channel, right click "Set Driven Key..." using this as driven, I key the driver to the custom attribute from the text box. Do this for all 3.

Presto... nothing happens. Obviously missing a step or am misguided.

Any advice? suggested resources?

Thanks in advance

Dont use driven keys if you need one to one connections.

Nothing is supposed to happen, you need to set 2 keys for every attributes at least, and you need to vary the driving attribute between setting the keys. What driven keys does it it remaps attributes trough animation curve. If you just want one to one connections use connection editor.
