about

nx_engine_lod_gate.nx -- ★ENGINE CONVERGENCE RUNG 2: LOD -- the INFINIGEN x ENGINE fusion, not a Nanite clone. GENERATIVE LOD (generated citizens): the being is re-sampled FROM ITS OWN SDF at the cell size its distance warrants -- no stored clusters, no streaming; the GENERATOR is the compression. (Nanite exists because Unreal must virtualize AUTHORED geometry; generated content gets LOD for free. Better than either.) AUTHORED LOD (corpus citizens): vertex-cluster decimation for the Stanford bunny (quality path = the ecosystem QEM organ, unbridged -- named residual). CAPACITY INVERSION (causal proof): the full-detail scene OVERFLOWS the mesh caps (tm_ovf fires -- it cannot exist); the same scene LOD'd fits and renders. T1 generative LOD ratios + determinism. T2 authored decimation. T3 perceptual (far LOD ~= far full, >=4x fewer tris). T4 capacity inversion. T5 evidence PNG. license_tier: ORIGINAL expect_exit: 0
