Decroative mod about ice and snow.
Renders a mesh randomly generated from a voxel terrain by marching cubes, which is generated from an octave noise based on block position.
Since most data is stored in GPU, it shouldn't cause too much fps drop (tested on my crappy GPU from 8 years ago: fps starts to drop slowly at around 400 blocks rendering at the same time).
Mod requires at least OpenGL 3.3 to run.
