NASA Lunar Terrain Visualization in Unreal Engine 5
summary
NASA engineers use LRO LOLA DEMs, GDAL and Unreal Engine 5 to generate accurate lunar terrain and compare methods: a quick Landscape (PNG/RAW import) pipeline that loses precision to Int16 but streams well; a high‑fidelity Nanite meshes with UnrealGDAL approach that preserves float32, applies spherical curvature, and runs fast but requires heavy memory and long mesh‑build times (hours–days); and a configurable clipmap runtime with RuntimeMeshComponent that trades artifacts for cross‑platform scalability.
