EasyBlockEditor

EasyBlockEditor is a building editor mod for Minecraft NeoForge 1.21.1, inspired by Litematica, developed with the LDLib2 framework.

It serves as both a building editor and a building management platform. The core concept: provide an in-game full-screen 3D UI editor, allowing players to design, edit, manage, and share buildings in a non-destructive way.

• Non-destructive Editing — Edit buildings virtually before applying to the real world
• Multi-format Support — Compatible with .litematic, .schem (Sponge), .nbt (Vanilla Structure), .schematic (Schematica), and native .ebe format
• Layer System — Organize buildings with layers (foundation, walls, roof, etc.)
• Workgroup Collaboration — Real-time collaboration with permission management
• Projection System — Preview buildings as holographic projections in the world
• Printer Mode — Auto or manual block placement consuming player inventory
• Version History — Full undo/redo with version snapshots
• Material Statistics — Real-time material cost calculation
• Block Heatmap — Visualize block type distribution with colors
• NBT Editing — Full block entity NBT editing and filtering
• Theming — Customizable UI themes via LSS stylesheets
