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 ...

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) ...

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