Heightmap terrain: .tch chunk packs, streaming with LOD, terrain painting, water and modifiers - terrain/<name>/terrain.yaml + <px>_<pz>.tch packs of 16x16 chunks (250 m, 0.5/1/2/5 m spacing), slices with crc-32 and optional zstd (vendored zstd 1.5.6 in ref/zstd) - heightmap_terrain [name] endheightmap_terrain directive replaces editorterrain - streamer: worker threads, camera + look-ahead loading, geomipmap LOD with skirts, pooled geometry - mat_terrain shader: up to 8 painted layer materials per chunk via texture arrays (opengl33); other renderers fall back to the dominant material - water bodies (outline + level), terrain modifiers (vertical profile shaping kept non-destructive) - F11 Terrain work mode rebuilt: chunks, sculpt, smooth, paint, point spacing, water tools
