Link scale to z axis
Is there and expression that I could use to link scale to z position? I have to 2d track that I want to fake 3d with. The track (using x, y, and scale) is good, but I want to be able to move something on the z axis. Is there a way I could link the scale to just the z axis of a layer?
Does that make sense?Mark Johnson

I don’t think you’ve provided nearly enough information, but it might look something like this:
minScale = ???;
maxScale = ???;
minZ = ???;
maxZ = ???;s = thisComp.layer(“your tracked layer”).transform.scale[0];
z = linear(s,minScale,maxScale,minZ,maxZ);
[value[0], value[1], z]where you’d have to supply the appropriate layer name and fill in the ???.
Now that I think about it though, you may need an exponential relationship between scale and z. That’s a different story.

I found a different workaround to my problem, but I will give this a try to see if it works for me..
thanks
