Wtf 80% of them look nearly exactly the same...
You mean they make squares? I like squares.
Hey it could have been worse, they could have been making dots instead, ugly round things. Also the pictures don't really do these emitters any justice, the shields "rotate" and other emitters spin around.
Need more details on droplet - a single droplet that's shaded with a transparency gradient?
Possibly yeah, I made a droplet but it's meh.
Current major issue is making a set of Splash textures. I'm trying to make complimentary Ground effects for the weather stuff, like a ground snow emitter that will create fluffy snow on the ground, and a Rain Splash emitter that will make it appear like the droplets are actually impacting the ground and splashing instead of simply "disappearing".
I'll start working on the fluffy snow :3
Edit: So fluffy...

But so laggy
