-- Snowdrift 0.1.1 by paramat

-- For latest stable Minetest and back to 0.4.6
|
|
-- Depends default
|

-- Licenses: Code WTFPL. Textures CC BY-SA.

|
-- This is intended to be used as alternative snowfall for the snow mod by Splizard.

-- The code is partly derived from weather mod by Jeija and snow mod version 1.8 by Splizard.

-- Parameters
|
