Well I was randomly playing maps in the tribe house, then I did /neige, then I released I could throw snow but it was invisible, there wasn't visible snow, I tested that in a lot maps and it is invisible in all of them.

If the snow hits something, it disappears. Might have to do with this?
Or does the snow just not show up at all?

Are you sure that you don't have particles off?

I just tried it in the tribe's house, and I saw my charector and snow, it was AWESOME!!!

And I donno whut it is.
