nx_gx8_ssao_gate.nx -- Gx-8: AMBIENT OCCLUSION, the contact cue that stops everything floating. Direct lighting alone carries no proximity information, so a shape resting ON a surface and one hovering above it shade identically -- which is why our figures and beacons read as pasted onto the scene rather than sitting in it. sg_ssao adds cavity darkening from the finished depth buffer. THE TEST THAT MATTERS is the neg-control: a naive depth-only SSAO greys out every receding floor, because downhill neighbours are always nearer. This gate renders a big SLOPED PLANE and requires AO to leave it essentially untouched, while requiring the crevice-rich humanoid to darken measurably. Passing ONE of those is easy; passing BOTH is the whole point of the opposite-pair sampling. license_tier: ORIGINAL expect_exit: 0
