Island Display Projector is a NeoForge mod for Minecraft 1.21.1 that lets server owners create interactive 3D Skyblock island displays for lobbies.

Place an Island Display Projector block, assign it to a Skyblock island, and it will render a floating miniature preview of that island above the pedestal without placing real blocks in the world. The mod can automatically detect supported island templates and also includes manual configuration for custom setups.

Operators can configure each projector in-game through a GUI, adjusting the island, display name, scale, height, rotation, visual effects, outline, nameplate, click command, and pedestal camouflage. Normal players can right-click a projector to run a configured command, such as creating an island, selecting a template, or opening a Skyblock menu.

Features:

Floating 3D island previews above lobby pedestals
Automatic Skyblock island/template detection
Manual config fallback for custom island displays
Per-projector GUI editing for server operators
Adjustable scale, height, rotation, offsets, and effect color

Requirements:

Minecraft 1.21.1

This mod is designed for Skyblock servers that want polished, decorative, and functional island previews directly in their lobby.
