Backdrops are variant forms of several normal blocks that do not obstruct movement but still retain other properties such as enchantment bonus or water redirection.
Backdrops are immune to normal breaking, but can be mined with another backdrop block.
Backdrops can also be broken by placing another block on top of them. This will cause them to drop as an item.
If a flammable backdrop burns, it will drop itself.
The block itself yields its backdrop (it can be crafted back).
Backdrops are placed like normal blocks.
A world tile can only hold one block, so it's not possible to have both foreground and background on a tile.
Backdrops give back their respective blocks when placed in the crafting grid.
- 1.25: You can no longer mine backdrops unless you are holding a backdrop.
