New weather effect?

[fr0st]

Basically, after 30 minutes of testing some volcano codes

 

[spoiler=..exactly]

 

 

i came up with the right function (2gudatmaths).. but then suddenly my mind was overrun by an idea.. what about a new weather effect?

(Before you ask it, no, i can't stick to one task. That is bad. That is me. Sorry) What I would like to do, is like snow biomes do.. when it's raining, instead of rain render a snowfall.. I wanted to make something similar for my custom biome (Which i will create, I don't have it right now).. so instead of water, i want ashes to rain. I don't really think I saw this before in any other mod, so that is why i am asking.. is this even possible?

 

Thanks in advance.

Ok, so today I looked inside minecraft's src, and I saw that rain and snow are rendered inside EntityRender.. so is there a way to add a new weather effect without changing base classes, which is something i don't want to?
