Citadel Desk questions
What is Citadel Desk?
Citadel Desk is a free Hytale schematic viewer and building planner for Windows. It helps you rebuild structures in Hytale using layer-by-layer plans and progress tracking.
Can I convert Minecraft schematics for Hytale?
Yes. Import a supported Minecraft schematic to create a Hytale build plan with suggested Hytale material replacements. Select a material row, then Hytale block, to review or change a match. Citadel Desk reads the block catalog from your own Hytale installation. This converts materials inside the companion; it does not export a native Hytale schematic or world file. Some Minecraft blocks have no exact equivalent.
Does Citadel Desk work offline?
Yes. Viewing and importing builds work offline, with no account or subscription required.
Which build files can I open?
Citadel Desk supports Minecraft Java schematics and structures, Litematica files, Axiom blueprints, Bedrock structures and world archives, and supported Hytale prefab and world files. The included README lists format versions and import limits.
Is Citadel Desk an official Hytale app?
No. Citadel Desk is an independent companion app and is not affiliated with Hypixel Studios.
