I've been trying to think of a method for fading a particle in and out of scene gradully i.e. without using a toggle. The specific example I'm thinking of is P_Water_Mist2.I initially thougtht there would be some controls in like Vector Material Parameters which you can poll in Matinaee. But all I found was float Particle Paraemter. I'm not sure how to access these paramenters but I don't think it would affect colour or alpha which is my current line of thinking.
I tried using the Set Particle Parameter in Kismet to change color to black but it seems to work more like a toggle, causing sharp changes and its not exactly the effect I'm after.As I don't know cascade that well is there any way to expose the alpha channel to matinaee or create a fade sequence that I can poll inside of Kismet. Or any other way you know of that can be used. Alternatively are there any maps that create such an transition with particles?
Thanks for any help or advice you can give.
I like playing with stuff!
