We'd be able to do optimisations like lightmaps and baked occlusion culling. Players would be able to learn their map. But without procgen maps would load faster. I pitched the idea of Procgen maps in Rust. The x-axis represents the average temperature (☌), and from the graph shows an average temperature of about 5 to 25 ☌.The y-axis represents the annual precipitation (cm) and shows an annual rainfall of approximately 200 cm (2,000 mm)
