This group of CTM folders adjusts the grass textures for vanilla biomes vs custom/modded biomes.

"basegame_grass" is loaded first and applies only to vanilla biomes while "neutral_grass" loads in greyscale variants of grass and foliage textures to avoid clashing with certain custom biome colors. 

IF YOU ARE EDITING THIS PACK:
Be sure that the 999_grass folder is last in the list of CTM files as these must be loaded last, and in this order for things not to interfere with each other.
