Update 11/25/13: Added AECC compatibility
Need a helping hand changing your 3D/2D Null layers into Light layers so you can use them for Plexus or Trapcode Particular? Well this short tutorial will show you how, plus you get a free script that does the actual work for you. HOORAH! 🙂

Free script? Yup, just look below the video for the download link. In the download you will get a .zip file that contains the NullSwapper_v1_5.jsxbin file and the NullSwapper.aep project file I use in the tutorial, so you can follow along if you like.
