To help fans create their own textured landscape (using tutorial map as template) i can mod it so that each block (18x18blocks) can have individual Blocks of textures that I can number (1-324) and then they can Paint by Numbers and change each block to allow paths, rough terrain etc.. without ever having to use blender or mods tools.
Some Original textures are frequently used by different maps and are simply recoloured-NFLGRS01,NFLFERN1-4 etc
