  Translate layer Z position to ‘Shatter’ Z position?

  Posted by Darren Gardner on November 23, 2007 at 10:43 pm

  What is the conversion formula to go from the Z position data on a 3D layer to the Z position data in the Shatter plug-in?
  The default Z position data in the Shatter plug-in is 2.00. The default position data on a layer is 0. It’s pretty clear that the Shatter plug-in Z position data is NOT 2 pixels deep. Does anyone understand what I mean? Can anyone help me out?

  I need this to line up two objects right on top of each other in the composition window. One object is a true 3D layer, the other is generated with the shatter plug-in.

  Thanks.

  With this position expression, a 3D layer appears to track shatter’s camera z position pretty well:

  z =( thisComp.layer(“shatter layer”).effect(“Shatter”)(“Z Position”) – 2)*450;
  [value[0],value[1],z]

  That’s great, Dan! This should really help! Is there an expression that works the other way – one that’s applied to the Shatter plug-in’s Z position that follows the 3D layer’s Z position?

  This seems to work:

  thisComp.layer(“other layer”).transform.position[2]/425 + 2;

  Note – 425 is probably a better multiplier for the previous expression as well.
