Block Displays
Block Displays render a vanilla Minecraft block in the world. They can be animated just like Groups.
Element Options
Displayed Block
The block state string of the block to display. Written in the same format as the
/setblockcommand.Examples:
minecraft:stoneminecraft:redstone_lamp[lit=true]minecraft:oak_stairs[facing=north,half=bottom,shape=straight]
The block state is validated against the Minecraft block registry for the selected target version. Invalid blocks are highlighted with a warning in the viewport.

Entity Creation
A Block Display always creates a minecraft:block_display entity when exported.
Display Entity Config
Right-click on a Block Display node in the outliner and select Display Entity Config to open its configuration.
