Holoplan

Build from a blueprint – right in your world.

Holoplan is a client-side schematic tool for Fabric. Capture any area as a schematic, show schematics as translucent ghost blocks, see at a glance what is missing or wrong, and get a ready-made material list. No server mod needed – it works in singleplayer and on servers.

Features

Capture

• Select areas with two corners – with a stick or by coordinates, multiple boxes per selection
• Save as .litematic or vanilla .nbt, including chest contents and other block entity data

Projection

• Show .litematic and .nbt files as ghost blocks with real block textures
• Move, rotate in 90° steps and mirror on X, Y or Z
• Layer mode: all, a single layer, up to or from a height, or a range
• Block filter: show only certain block types – or just the block in your hand
• Placements are saved per world and restored when you come back

Check & materials

• Colored markers for missing blocks, wrong blocks, wrong orientation and extra blocks
• A list of every difference with exact coordinates, plus a live counter in the HUD
• Material list (needed / missing) in stacks and shulker boxes – copy it or export it as .txt

Easy Placement

• Optional: right-click places the block the blueprint expects, facing the right way (stairs, logs, slabs, furnaces, pistons, observers …)

Comfort

• One clean window with five tabs: Projection, Files, Selection, Check, Options
• English and German, all keys rebindable, client command /holoplan
• Fast even with huge builds – ghost blocks stay on the GPU

Versions

One file per Minecraft version: 26.3, 26.2, 26.1 – 26.1.2, 1.21.11, 1.21.10, 1.21 – 1.21.1, 1.20.1. Requires Fabric API for the same version. 1.21.9 is not supported – please use 1.21.10.

Good to know

• Schematics go in .minecraft/schematics/ – the same folder Litematica uses, so existing files show up right away.
• Holoplan never places blocks by itself; Easy Placement only picks the orientation. Strict anti-cheat servers may dislike the brief look-direction change – check the server rules first.
• Chest contents can only be captured fully in singleplayer.
• Chests, signs, beds and liquids show up as a translucent box instead of a model.
• Not tested with shader mods.
• Not affiliated with Litematica; it just uses the same file format.
