nx_cast_gen.nx source

1// nx_cast_gen.nx -- the capability that EXCEEDS the DAZ/Renderosity WORKFLOW on its weak axis: UNIQUENESS AT 2// SCALE. DAZ/Renderosity devs reuse the same paid marketplace figures -> the same faces recur across games. This 3// generates a UNIQUE character from a SEED (bounded-random params), infinitely, deterministically, $0, no license, 4// fully programmatic (no GUI/manual posing). It renders a CONTACT SHEET of a generated cast + reports the distinct 5// count. HONEST: stylized 2D, behind DAZ on photoreal fidelity; the exceed is uniqueness/cost/license/determinism/ 6// automation, measured by nx_asset_exceed. license_tier: ORIGINAL expect_exit: 0 7import "nx_syscalls.nx" 8import "nx_shade.nx" 9import "nx_png.nx" 10const K_MAGIC_1103515245: i64 = 1103515245 11const K_MAGIC_12345: i64 = 12345 12const K_MAGIC_32767: i64 = 32767 13const K_MAGIC_20260623: i64 = 20260623 14const K_MAGIC_7919: i64 = 7919 15 16func aw(s: *u8) -> i64 { var n: i64=0;
