Better Grass is a OptiFine feature, which makes grass, Mycelium and Podzol textures get on the sides of the blocks if the grass is on a shallow slope, but if there is a drop of more than one block, it will have the regular texture. The mod was created by MrMessiah and D'oh. There were only 4 versions, then it was patched. (This is unclear, and i don't know what to do about it to make it more clear)
History[]
The mod was released on September 20, 2010, the same day MrMessiah joined Minecraft Forum. In a few weeks, there were released 3 new updates. Meanwhile, MrMMods was created including Better Light, Better Grass and SimpleMap, and later SMChat. On February 19, 2011, she released the last update, which fixed some Better Grass' bugs. After this, Better Grass became obsolete. In early versions of OptiFine, the Better Grass feature was added, which made players satisfied.
