i read this page here http://greyminecraftcoder.blogspot.com.au/2014/12/block-models-texturing-quads-faces.html
and i thought i understood how uv mapping worked. however on another one found here http://minecraft.gamepedia.com/Model
it says the the down uv mapping for a standing torch is from [7,13,9,15] to [7.6.9.8]. If the down face is right in the middle of the block, is only 2x2 pixels big, and the entire thing only stands 10 pixels high i dont understand where the numbers 13 and 15 fit into this at all. If im not mistaken the down face is the x and z coordinates right? How exactly is uv mapping measured i just dont understand. Heres the json file im referring to
File: torch.json
