Hello,   I am currently trying to implement a custom 'Material' (as in Iron/Gold/etc) pipeline in my mod. To do so I am generating ores, ingots, etc. using a single base texture and a material's assigned color. I understand how to achieve desired results for coloring Items and single-layer blocks, but I am having trouble figuring out how the following can be done:     I have two texture files, the stone, and the white ore vein overlay. The block would have the base layer of stone.
