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 armor stand
  
• Move hologram (third person only): Stick
  
• Block validation: Iron ingot
  
• Material list: Tab button (keyboard), book icon (touch)
  
• Armour stand controls: Give item or hit
  

  [!WARNING] Player controls may be unreliable, but armour stand controls will always work.
