I created five Mediterranean biomes for an RTS game using Unity HDRP in 2023, with two full levels per biome. Terrains were sculpted in World Creator, Microsplat was used for terrain shading, and Vegetation Studio for procedural scattering. Textures were created using Substance tools. Each level was 4 kilometers square, with several showing flowing rivers and open water horizons. I was also responsible for lighting, atmosphere and performance optimization.
