The Marble, limestone, iron, gold, diamond and concrete blocks were done by myself. I did change or repeat some of the blocks with different colors because I simply could not tell what the block was meant to be.
The cobblestone, glass, glasspane, lightstone (there's only one but it's really great!), birch/jungle/oak/spruce planks, redstones and stonebricks come from Norte's texture pack. It's made by Bonmucho and he granted me his permission to add what he has done to this! MANY thanks to him!
For some of the remaining blocks like sandstone and obsidian (I'm sure there's more I just can't remember what they are) I would suggest looking up Alexmania's texture pack. He also hasn't done all the blocks . I tried asking his permission two weeks ago but my message was never read so I won't be adding them to this pack.
