Camera X and Y position matches Null X and Y position?
by Tim West on Sep 11, 2009 at 11:44:04 am

Hi,

I'm trying to build a composition in which a camera's X and Y coordinates correspond with the X and Y coordinates of a null object - e.g. a camera & target set up similar to the target camera in C4D.

Can anyone help me with these expressions (or is there a better way to achieve this?)

Thanks,

Tim

UPDATE:

I've managed to create exactly what I need EXCEPT one thing ....

I have my 3D Null layer's ('control') position controlling the anchor point of my 3D content layer ('Map').
However - I only want the Null layers X and Y (not Z) values to be mirrored by the content layer (so the content layer's Z position remains at 0 at all times.

Can anyone show me how to specifically target position X, Y or Z values of 3D layers?

Thanks for your time,

T

thisComp.layer("control").transform.position

p = thisComp.layer("control").transform.position;
[p[0],p[1],value[2]]
