  .toWorld(anchorPoint) in PositionZ is displaced

  Posted by Vera Steinbeck on April 1, 2019 at 5:49 pm

  hey there!
  i have a problem with the generate-beam function.. i have the beam building a line and at the front of it i need a light following as emitter for particular.
  now everything worked fine in 2D, but in 3D, the Z-axis is off and i can’t find out why :/

  my expression simple: i have a linear expression on the light-position that moves from circleA to circleB along with the “time” setting from the beam-layer.

  

  if i stay in the same z-Axis the light follows without a problem. it i have a longer travel from about z0 to z300 then the light is delayed..
  does somebody have a clue, why this is happening?

  help would be greatly appreciated!

  Time = thisComp.layer(Beam).effect("Rope - Controls")("time");
BeginningLayer = thisComp.layer("1").effect("Rope - Start")("Ebene").toWorld(anchorPoint)
EndLayer = thisComp.layer("2").effect("Rope - End")("Ebene").toWorld(anchorPoint)

  linear(Time,0,50,BeginningLayer,EndLayer);

  //There may be typos in the code - i simplified it

  Is the Beam effect on a 2D layer? If so, try using toComp() instead of toWorld().

  hi dan!
  thank you for your time! ????

  yes, the beam effect is on a 2D layer.. i tried using toComp(anchorPoint) but then the positionZ was way back in zPosition, about 1500

  hmm…
