Invisible Bedrock

Invisible bedrock is an invisible block used to create a world boundary around Old worlds and the void floor in Bedrock Edition.

Invisible bedrock is fully transparent in rendering and thus is completely invisible.

The texture used for invisible bedrock in the inventory is that of stone, but it fills the whole slot, unlike stone. If the player lands onto invisible bedrock, particles from the stone texture can be seen. In Pi Edition, it used the grass texture instead, as the game is based on an old version of Pocket Edition Alpha before the texture was changed to stone.
