Placeholder texture

A placeholder block is a block or texture used in place of another block or texture that is missing. Various examples of placeholder blocks include Info_update, Reserved6, the Java Edition missing texture block, and .name.

Info_update
Info update is a debugging/placeholder block exclusive to Bedrock Edition that generates in place of blocks that were removed or not yet added. You can read about it more on its main page, Info update.

Obtaining
The block cannot be obtained, without breaking it when already in a world. Its tool requirements are unknown.

Even in Creative, it cannot be obtained via or, and as such can only be obtained through inventory editors, or other methods such as using behavior packs to change loot tables.

Usage
The update game blocks are a set of two similar placeholder blocks present $$. These blocks are placed in the world when the game detects an invalid block ID. (This means it is the substitute to the missing texture block that appears $$) Shovels are ineffective against this block despite the dirt sounds and texture.

They can be obtained only via inventory editing or mods. This block is used only for blocks with invalid IDs. If the block ID is valid, but has no texture, it appears as a magenta black checkerboard block instead of this block.

The block's texture is shared by reserved6.

Reserved6
Reserved6 is an unused former placeholder block.

Obtaining
Even in Creative, it cannot be obtained via or, and as such can only be obtained through inventory editors, or other methods such as using behaviour packs to change loot tables.

Information
reserved6 is an unused block with a completely off-white texture present $$. It acted as a placeholder block for fire between and, due to a bug in fire spreading mechanics that caused fire to spread to any block. Before becoming unused, the block was called .name and it had the texture of a stone block. In, fire returned with fixed spreading mechanics, replacing reserved6. Its data value, however, changed to ID 255. Currently, it can only be obtained through inventory editing.
