MapGen V22 supports a wide array of export formats, including raw 16-bit PNG heightmaps, Unity Terrain Data (.terrain), Unreal Engine Landscape Layer Info, and even CMYK TIFFs for print cartography. A new addition in V22 is the "GameMesh" output, which generates optimized LOD (Level of Detail) meshes directly for Godot 4 and Unity 2023 LTS. mapgen v22
The interface favored composers over coders. A visual “narrative palette” let teams paint motifs onto a canvas: drop a “fortress” brush to increase defensive geometry in a region, smear “desolation” to multiply collapsed structures, or stamp “market” to spawn clustered stalls and NPC paths. MapGen v22 output was exported as layered JSON: geometry, semantic tags, simulated history. Artists, writers, and level designers could iterate separately but remain in sync with the same generative story. | Feature | Vanilla (1
