   I think this is something staring me in the face but I am not seeing it.
   
   I am trying to dissolve an image from left to right and have tried many approaches. It works well as doing the whole image or part of the image but I can't seem to get it to work slowly going across the image.
   
   current code fragment is below.
   
   Any help would be appreciated.
   
   Thanks

   Actually I just took a fresh look at this and it looks like a custom emitter that uses the set property of the rectangle zone may work. I'll try this the next opportunity I get and see it if works unless someone else mentions otherwise.

   Just for reference, if anyone else is trying this. My theory worked without requiring any customization of anything. This one little modification saved a HUGE amount of overhead (10s of megabytes) by not having to achieve the same effect in AE and importing the result into Flash.

   Hi chien. Sorry I wasn't around to help but I'm glad you worked it out. Nice solution.
