L3DT vs Mapgen4

L3DT is a terrain-generation and editing application for game developers and digital artists creating large 3D worlds. Its design map lets users define terrain characteristics and effects such as altitude, roughness, lakes, climate, erosion, terraces, cliffs, and volcanoes. A 3D heightfield editor provides mouse-driven brush tools. L3DT generates ground textures, alpha maps, and light maps, including shadow casting and bump mapping. The free Standard Edition supports heightfields and texture maps up to 2049 × 2049 pixels. Professional editions support larger maps through disk paging: heightfields up to 131,072 × 131,072 pixels and textures up to 4M × 4M pixels. Professional Indie costs $34.95, paid once; Professional Commercial costs $149.95, paid once. Both include two years of free upgrades. Formats include BMP, JPG, PNG, TGA, DDS, OBJ, COLLADA, Terragen TER, and Virtual Terrain Project BT, with GeoTIFF import. L3DT supports plugins, custom filters, and Python and ZeoScript scripting through plugins. It is a Windows application; Linux use through Wine is recommended for testing because bugs may occur.
