Anti X-Ray RP

This is a free and open-source resource pack that blocks the use of X-ray resource packs when applied to a world, including local worlds, Realms, and servers.

It restores the block shapes of all affected blocks without overriding any textures of other resource packs. That way, only the block shapes that make X-ray possible are blocked, allowing the players to still use other local packs without X-ray functionality.

Warning: This resource pack is a best-effort attempt to prevent X-raying. There are ways to bypass this, but it will take bad actors more effort and stop non-tech-savvy people from doing so.
