Animate DUPEND value

I have two questions:

How can I animate the value of DupEnd. I want to create an animation, where the dupliframes are created during the animation.

The second question:

How can I limit the follow curve to one dimension. An example is a cube follws a 3Dimensional curve. 'It should rotate according to the curve but the z axis of the cube points always up to the worlds z axis.

thanks in advance for your help.
cheers,

  1. You can’t do it in the IPO Editor, maybe with Python (ask Gabio nicely if you can’t do it yourself).

  2. Turn off the CurveFollow button.
