Opacity by Z-value
Hey gang…
I’ve distributed a bunch of photos into a scattered sphere with 3d Assistants…now I’m looking for an expression that turns everything further away than 0 invisible (I’m planning on doing the opposite to a duplicate of the comp in order to put pics in front of and behind a keyed actor).
I’m using:
if (position[2] > 0) 0 else 100
…to no avail…
Thoughts?

I’m not familiar with 3D Assistants, but my guess is that your layers probably have complicated child/parent relationships (don’t we all?)
If that’s the case you’ll need to use:
if(toWorld(anchorPoint)[2] > 0) 0 else 100;I can’t error check that code right now, but it looks right from where i’m sitting 🙂
