- 8 cosine-weighted hemisphere rays per pixel (inline ray queries, SM 6.5) - Distance-weighted AO: quadratic falloff (1-hitT/aoRadius)² instead of binary hit/miss - World-space hash seed: voxel coord + tangent-plane frac position (stable, no flicker) - Bilateral blur pipeline: 2-pass separable (H+V), radius 6, depth+normal edge-stopping - 4-pass dispatch: shadow+rawAO → blur H → blur V → apply - AO written to separate R8_UNORM texture, blurred, then applied to color buffer - Debug mode (F5 x3): grayscale AO visualization
