Thanks for diving in and responding.
Looks like your helping out the rest of the forum too.
I am at the moment using several instances of particular on one layer and many lights differently named to produce different sized particles.
Problem is the different instances of particular don't interact together spatially.
They just comp on top of each other.
Please see the pics in my previous posts to see what i'm talking bout. If you have a min to spare for me.
Looks like i'll have to make do with the restrictions.
If you could produce diff size particles from each light emitter with one instance of particular then all would be well with the world. Well not the whole world. Thinking about it in the big scheme of things..it hardly matters...i'll just crawl back into my little corner of the petri dish. There are bigger issues at stake in the world at the mo. Crickey many people are literally fighting for there lives...puts some issues into perspective eh...
my best regards to you and yours...Max
