COE Structure is an addon for Create Ore Excavation that enhances the ore vein experience by automatically placing a visible NBT structure at the center of each hidden ore vein when the chunk is first loaded.

features:

Automatically spawns a customizable NBT structure at every ore vein center, making veins visible without needing the Vein Finder item

• Built-in ore generation restriction system — configure a radius around a center point (X/Z) within which ores are allowed to generate, suppressing all ore generation outside that area

• All settings are configurable via a per-world server config file (serverconfig/coestructure-server.toml)

How it affects your experience:

No more wandering blindly looking for veins — the marker structure acts as a visual beacon visible from the surface

• Server admins can define a strict ore generation zone, perfect for modpacks that want to encourage exploration toward a specific area or create resource scarcity outside a defined region

• Marker structures can be themed to match your modpack aesthetic without touching any code

requirements:

• NeoForge 1.21.1

• Create Ore Excavation
