Originally in the default Minecraft textures, ores have remained almost the same even past the Jappa re-texture (the stone part changed not the ore) and so I brought it upon myself to change them. Default has 4 different ore textures, my texture pack has 6 different ore textures and this is when taking quartz into consideration. I hope these changes are refreshing due to the lack of change they have had even through the re-texture.
I had many goals working on this project, a few are as follows:
1) Make the ores look like clumps of ore in stone
2) Make most ores visually different from one another
3) Make redstone more accurate to it being a dust
4) Make iron and gold similar to reference that they both need to be smelted and how both their ingots and nuggets appear similar
5) Make coal and lapis similar to reference the lumpy appearing coal and lapis items
6) Make emerald pointed similar to it's item
Be aware that this does NOT change quartz as it already has a unique and appealing ore texture! (quartz is also the most recently added ore)
