## What it is
Cesium for Unreal is an open-source Unreal Engine plugin that brings the 3D geospatial ecosystem into Unreal Engine, providing a full-scale WGS84 globe and runtime streaming of real-world 3D content via 3D Tiles. It integrates with Unreal's editor, Blueprints, physics, and rendering, with optional Cesium ion cloud services for curated global content.

## Use cases
- stream real-world 3D cities and photogrammetry into Unreal Engine
- build a digital twin with accurate WGS84 globe coordinates
- visualize terrain and satellite imagery at full Earth scale
- create flight or drone simulators over real-world terrain
- stream 3D Tiles from a private self-hosted server into Unreal
- add geospatial context to game levels with real buildings and terrain

## When to choose
- you need real-world geospatial content inside Unreal Engine
- you want to stream massive 3D Tiles datasets at runtime
- you're building simulations, digital twins, or geospatial games in UE4/UE5
- you need an accurate full-scale Earth globe with physics and character interaction

## When to avoid
- your project doesn't use Unreal Engine
- you only need lightweight web-based globe visualization (consider CesiumJS instead)
- you need offline-only rendering with no streaming content
- you work in a different game engine like Unity or Godot
