about

nx_engine_scene_gate.nx -- ★ENGINE CONVERGENCE RUNG 1: worlds + beings + assets in ONE scene, ONE renderer (the Unreal lesson: Nanite geometry + MetaHumans + PCG coexist as ENGINE CITIZENS, not island demos). This scene: TERRAIN layered-noise heightfield (the banked Minecraft-pipeline lesson: octaves + biome-ish surface colours) BEING the holistic human, WALK-POSED, polygonized IN PLACE onto the terrain (SDF -> mesh at world coords) ASSET the Stanford bunny (corpus citizen), placed beside the being -- all in ONE trimesh buffer through ONE z-buffered render (SSAA hero shot). Visibility proofs are CAUSAL: remove a citizen -> the image must change. T0 composition, T1 renders, T2 causal visibility, T3 determinism, T4 evidence. license_tier: ORIGINAL expect_exit: 0
