Hi, I have a simple question.

I'm trying to animate the extrusion process of a simple cube polygon. I would like to explore a simple shape and animate the process of it evolving into a complex shape. I've tried setting keyframes, and this seems great to set transform attributes, etc., but does not seem to set extrusion.

For example, If I extrude a face on a cube and set a keyframe at frame 20, the extrusion is still present when I rewind to frame 1.

I would also like to be able to subdivide a face, and just extrusion one of the subdivisions and animate this as well.

Is this possible in Maya?
