It seems you must use a scalar state node with a change_range. Set the
min/max for the old range with your X image size for example.
Use two mix_2_colors with two scalar state if you need X and Y in one rgb
image pass.

Looks
like this hasn't been brought up in a couple of years. Has anyone come
up with any new workflows on getting a position on an object in the
screen X/Y space? I saw there were some scripts that use something like
this for subregion rendering. I just need the data so I can feed it
into After Effects. How do you use the Scalar State node for this
application?<br><br>Thanks.<br><br>---<br>Unsubscribe? Mail <a href="mailto
