about

nx_gi_gate.nx -- ★R3 of the Infinigen ladder: SINGLE-BOUNCE GI (irradiance cache). Verifies the PHYSICS signatures, not just "pixels changed": T1 SCOPE: sky pixels are BYTE-IDENTICAL with GI on (bounce light cannot reach the sky) + terrain changed T2 ★SHADE-FILL: relative brightening in the darkest terrain quartile >> in the brightest (bounce dominates where direct light is absent -- the defining GI behaviour) T3 ★COLOURED bounce: in shade, green gains more than blue (sunlit GRASS bleeds green -- colour transport, not a flat ambient boost) + panel knowledge/nx_gi_panel.png (off | on | amplified difference) license_tier: ORIGINAL expect_exit: 0
