Some time, maybe years ago, there was this pack that replaced default wood, iron and whatever textures for different ones....different colors, more high quality i guess. i looked around for it with no luck. and no this isn't the flat textures. they were actual textures. i hope someone knows the pack i'm talking about because i kinda really want to use it again.
also i'm pretty sure it was posted on "show your hud modifications" at some point, although i don't know in which page.
