XRay — see through blocks

For those who don’t know, X-Ray allows you to see through most blocks to find ores more easily. It functions as a resource pack that changes the textures of common blocks, like Stone or Gravel, to be transparent. Additionally, the addon highlights valuable materials like Diamond Ore so they are easier to spot. Hazards that could endanger your character, such as lava, will also be visible through the walls.
