About

HoloPrint is a web app that converts MCBE structure files into resource packs showing holograms of builds. It builds off the work of Structura, a similar project. Both Structura and HoloPrint aim to recreate the experience of Java Edition mods like Litematica and Schematica for Bedrock Edition users through resource packs.

Usage

Note

On Android the Structure Block export button is hidden; please use this pack to add it back.

1. Use a Structure Block to export a .mcstructure file. To get a structure block, run the command /give @s structure_block.
   
   
2. Go to https://superllama88888.github.io/holoprint, select your .mcstructure file, and tweak settings.
   
3. Generate and download your resource pack (.mcpack).
   
4. Apply your resource pack and place an armour stand in your world.
   

Hologram controls

• Toggle rendering: Stone
  
• Change transparency: Glass (sneak to decrease, stand to increase)
  
• Change layer: Planks (sneak to decrease, stand to increase), or changing the pose on the armour stand
  
• Move hologram (third person only): Stick
  
• Block validation: Iron ingot
  
• Material list: Tab button (keyboard), book icon (touch)
  
• Change structure: Arrow, or hit armour stand when holding nothing
  
• Armour stand controls: Give item or hit

Warning

Player controls may be unreliable, but armour stand controls will always work.
