So just trying to change my biome ID's for the mods I have in my pack, but the numbers in mods like Biomes O Plenty are so cluttered and not in order (it doesnt go from like 40-220 but has random numbers all cluttered) that I cannot simply look for individual numbers and change it that way. So I intend to just change it so that each mod has its own range of biome IDs (for example Biomes O Plenty 40-200, Tropicraft 201-210, etc), but im not so sure what the ID numbers I can use safely are, without conflicting with vanilla biome IDs or anything.
I've also heard that you cannot use biome IDs over 256, is this right?
