Hello everyone. Me and 2 friends are making a mod for Minecraft 1.8.9 (because they changed a bunch code stuff in 1.9) The Problem is, I created textures for amethyst, kunzite, sapphire, topaz, emerald and diamond. We'd like to change diamond and emerald spawnrate and texture so it fits the others. We can't find out how to do that. Anyone got an idea? Attached are the ruby, topaz and diamond to see what I mean with "fits the others".
