nx_char_layers_gate.nx source

1// nx_char_layers_gate.nx -- the LAYER STACK proven: a nude base + [tunic + belt + hat] composes into one clothed 2// character, all layers rendering, on the photoreal shader. Proves (T1) the stack adds each layer's parts, (T2) 3// multiple layer materials render (crimson cloth from tunic+hat, steel from the belt), (T3) the stack reads as a 4// covering outfit (delivered tier = clothed).
