I am trying to make a comp that has two slider controls.
These two sliders represent the "Far Point" and "Near Point" of the layer they are controlling.
I want to be able to traditionally key frame the x,y position, but I want the slider controllers to control the z position only.
Imagine a layer with two key frames. The first key frame would grab the z-position from the "Far Point" controller and the Second keyframe would grab the z-position from the "Near Point" controller. Ideally I would like interpolation between the far and near point as well.
Can this be done?
