Get absolute transform values? (3D parented objects)
I’m building a pretty simple animation, but I know I could use this in other places too.
Basically its a 3×3 grid of rectangles that rotate in 3D space and reveal something else on the other side.
But I want to be able to write an expression so that when the front or back pieces reach a certain degrees, their Opacity goes to 0, so you can see the other side. Had issues with z-fighting and stuff, so figured this would be way more efficient than manually cutting layers.I found a Dan Ebberts script in here, but it was for 2D layers and I couldnt get it to work with 3D ones.
Any ideas?

Not exactly answering my question about absolutes, but I guess this works in finding it sorta manually:
angle = transform.yRotation%360-thisComp.layer(“Null 1”).transform.yRotation;
if (angle > 90)
0
else

I’m guessing you’re not talking about this one:
