After playing minecraft and messing with the new biome, I discovered a peculiar and smart way to render snow effects.
An animated snow texture was applied to two intersecting planes, and then each set of planes spawned squarely around the player about 24 times to form a tube-like encasement for the player.
When the player moved, the snow planes were created so that the player was never out of the snow “tube”.
I can create a good ‘falling snow’ texture, and you (the coder) should be able to create a piece of code that would allow this to be possible clientside.
If this were done correctly, we could have a decent snow effect that doesn’t use any laggy particles!
