Your transparent glowstone doesn't work because of how MC chooses what to render. If it kept every block in RAM it would run out of space very fast, so MC only stores faces that are next to a transparent block (like air or water) in RAM. Thats why when you glitch through a wall, you see caves. Having glowstone as invisible means you can see through the blocks below it, since they are not rendered, creating the appearance of a hole, as seen in the photo above.

well, there should be a secondary version of the texture pack where pitch black darkness is green, so that players can make evil creepers stalk them in the darkest of caves! there should also be another version with a different greenscreen block, because some players use the redstone lamp. other than that, great work!
