Is there a way to control the particluar particles alpha matte where as you would see the composition at 100% opacity then the particles would animate from left to right as as the particle position was animated the alpha matte opacity would becoming more visible until the particles take on the composition ?
Currently using particular I'm using AE alpha matte and the particle take on the composition from start to finish I want the particles to over time take on the alpha matte sorta like a transision ?
I've tried dozens of methods and although learning more about particles, this problem I cannot figure out, it doesn't matter if I use particular or particle world although I prefer particular because it's faster.

Hi,

Not sure if I entirely understand your problem? What is wrong with the way you're doing it now? So the way you are doing it now is using the particles as a matte, in order for it to act as a transition. Is this not working for you?

No, it wasn't working because I needed to have the particles not cause the transition until a specific time which means that the composition is shown then at a frame would the track matte particles come in, but because you can't turn on and off track mattes, and I tried using the opacity switch but that just turns my whole composition blank when the opacity is set to 0% which I don't want. I have gone with another method that looks alright but I thank you in your support.
