I need a simple, performance-friendly terrain for ARMA 3 that sits in the 5–15 km² range. The entire map should be a barren desert—no structures, vegetation, rocks, or ambient clutter—just the road network I will sketch out for you in advance. Accuracy to my layout matters more than visual polish, so keeping the asset count to an absolute minimum is essential. You may use Terrain Builder, World Creator, L3DT or any comparable workflow, as long as the final result imports cleanly into ARMA 3 and runs without errors on a dedicated server. Deliverables • Compiled .pbo and any required addons ready to drop into an ARMA 3 mission folder • Source project files (heightmap, layers, roads shapefile, config.cpp) so I can make tweaks later • A short text file outlining the build steps or tool versions used, just in case I need to rebuild Acceptance criteria • Playable terrain size between 5 km² and 15 km² • Only desert terrain textures plus my custom road network—nothing else placed • No script or engine errors when loaded in single-player or multiplayer editor If this sounds straightforward to you and you’re comfortable turning around a clean, empty desert quickly, let’s talk timing.
