about

nx_face_expr_gate.nx -- ★R-FACE EXPRESSIONS: muscle-driven facial expressions on the inside-out anatomical head (the digital-human R3 face rung + the engine MetaHuman-axis face half). The anatstack already models the facial muscles (zygomaticus/frontalis/orbicularis); an expression CONTRACTS one and the overlying fat/skin follows. The proof is CAUSAL and PER-PART (as_part_sdf isolates the moved structure, not the smooth-union soup): a smile lifts the malar fat (a point above the neutral cheek FLIPS inside); surprise drops the jaw (a low mouth point fills) and raises the brow; a frown lowers the brow. Plus a whole-face render imdiff (the expression is VISIBLE) + evidence. T1 build. T2 causal per-part flips. T3 visible (render imdiff). T4 determinism. T5 evidence strip. license_tier: ORIGINAL expect_exit: 0
