about

nx_worldpop_gate.nx -- ★SOVEREIGN INFINIGEN: POPULATE a world with vegetation. Render a procedural landscape, then place procedural TREES on the terrain (projected + distance-scaled, painter's order far->near) = a LIVING landscape. Proves the modules compose: nx_worldgen (nature) + nx_treegen (vegetation). T1 the populated world renders with markedly more canopy-green than the bare world (trees were placed) T2 determinism + PNG knowledge/nx_worldpop.png (bare world | populated world) license_tier: ORIGINAL expect_exit: 0
