SRTM

How I replaced a proprietary terrain bundle with a fully procedural environment generated from open-source data — hundreds of buildings with window textures from OpenStreetMap, terrain-hugging roads, satellite-driven vegetation, and multiple ground and air entities — all built at runtime in a headless Unity Docker simulation.

How I replaced flat brown terrain and solid-color sky in a headless Unity 6 Docker simulation with real satellite imagery, SRTM topography, and a custom panoramic skybox — all fully air-gapped, no runtime network dependency. Includes NVENC GPU encoding, custom shaders, and every dead end along the way.
