Documentation How to use Simply add the “Simple Screen Space Ambient Occlusion” to any camera you wish to use the efect. Parameters • Axis pattern: Texture used for the interleaving pattern. Should be a 3x3 texture, you can re-generate the included one using SimpleSSAO->Generate Axis Pattern Texture, or modify AxisPatternGenerator.cs to create a custom one. • Quality: infuences amount of samples taken by the occlusion shader. Higher quality settings take more samples, and will look better but perform worse. • Radius: maximum reach of the efect in world space units. • Radius range: Minimum/maximum radius in pixels. Since the radius is scaled by pixel depth, pixels further away from the camera might get a very small radius. This parameters clamps the radius so that it doesn´t get too small or too big. • Occlusion Bias: Width of the occlusion cone considered by each pixel. Set it higher to reduce self-occlusion. • Occlusion Ofset: Amount of base occlusion. Increasing its value will cause fat surfaces to turn grey, occlusion will be subtracted from corners and added to crevices, resulting in increased contrast. • Occlusion Exponent: Controls the shape of the occlusion curve. A value of 1 means linear occlusion, a value of 2 quadratic occlusion, and so on. • Occlusion Intensity: Modulates the amount of occlusion contributed by each pixel. • Luminance modulation: Amount of occlusion removed from high-luminance areas. This can help reduce AO in areas directly hit by light, which avoids washed out colors and keeps AO to shadowed areas only. • Bleeding Intensity: Modulates the amount of color bleeding. • Downsampling: amount of dowsampling performed when calculating AO and color bleeding. A value of 1 means full screen size, 2 means half-screen resolution, 4 a quater-screen resolution. Higher values will increase performance and decrease quality. • Blur: on/of blur toggle, useful for visualizing raw unfltered output. • Blur Depth Threshold: minimum depth diference between blurred fragments. • Blur Normal Threshold: minimum normal diference between blurred fragments. • Visualization: Allows you to visualize the occlusion or bleeding bufers only. Useful when fne-tuning efect parameters. Support / Contact If you have any suggestions, questions or issues, contact the developer at: support@virtualmethodstudio.com
