Install in the game only; not needed on the server
Requires Sodium (or Embeddium^).
Small optimization by removing the invisible sides of the bottom/ top layer of the world. For the player, these sides are visible only when necessary. (The bottom layer of polygons in the Overworld will be deleted, and the bottom and top layers in the Nether). While the mod is themed around Bedrock, the mod makes no actual checks for block type and can provide a benefit even on floating island worlds (such as mini game servers!)
^Only on NeoForge 1.20.x, or the Special Embeddium build for 1.21.1
