Fun Fact: The Polished Blackstone Bricks texture has 2 skulls in it! It's quite subtle in-game, and Jappa recently confirmed that it has skulls when someone asked him on Twitter. Thing is, the 1.17 texture has 2 extra skulls, so it's no longer as subtle. That's where this pack comes in. It reduces the number of skulls back to 2. I didn't decide to port the 1.16 texture because 1. The skull pattern is more repetitive in 1.16, and 2. The 1.17 texture is a bit smoother than 1.16's. In case you were wondering, the brick version has been done too.
