Use commands in Creative mode: `/give @p barrier`, `/give @p structure_void`, or `/give @p light_block`
Enable cheats or operator permissions on the world or server
Use `/fill` or `/setblock` with block IDs that are invisible or non-solid
Place and then hide blocks with pistons, water, or other blocks if you want a temporary “ghost” effect
Use resource packs or shaders to make visible blocks appear invisible client-side
Use mods or client-side add-ons that add invisible or ghost-like blocks
Use debug tools or map editors to place special blocks that behave like ghost blocks
In survival, rely on server glitches only if the server allows them, since they are usually patched and inconsistent
