  Headscratching 3D error: Z-position

  Posted by Filip Vandueren on August 28, 2005 at 2:29 pm

  OK,

  here’s something very strange:

  • create a new comp.
  • create a small solid (20x20px)
    give it a square mask, then delete 1 point so you have a mask that’s not symmetrical.
  • Make it a 3d layer.
  • Make sure the mask is visible in the viewer
  • scrub back the Z-position:
    you’ll see the layer grow bigger as it approaches the camera.
  • scrub it past the camera and you will see the mask re-appear and becoming smaller again, but now it’s mirrored…

  The layer is not rendered, so you only see it if it’s selected and you have show masks enabled.
  But the nag is that when you do an expression like toComp() you get a totally wrong result.

  I bumped into this when using the beam effect to connect two 3d-layers, see the thread “3D Space – line between 2 points expressions”

  Help ?

  That is strange indeed. You might want to drop a line to aebugs@adobe.com.
