  Particular Pickwhip Bug

  Posted by Chris Keller on June 1, 2009 at 9:26 pm

  Hey there,

  has anyone ever tried to pickwhip the Motion Blur->Type property of Trapcode Particular? It keeps on returning 6 (instead of 1 for “Linear” or 2 for “Subframe Sample”). When reading the value with the AE script language, the correct value is returned, but the expression language screws up…

  Hmmm… I always get the strange ones 🙂
  Thanks for your help!

  Got it! The problem is that Particular has two properties called “Type” – one in the Aux system and the other in Visibility. Now if you tell AE to grab thisComp.layer("Particle Layer").effect("Particular")("Type"), it will look for the first property called “Type” and return its value – and the Aux system comes before the Visibility.
  A workaround is using match names: thisComp.layer("Particle Layer").effect("Particular")("tc Particular-0063"). By the way, other effects (like Shatter) have the same problem.
  Probably plugin developers should take care not to create double names.

  Best,
  -Chris
