Instructions for use

Screen-Space Ambient Occlusion (SSAO) technology is a real-time rendering technique based on screen spatial data, used to enhance the surface lighting realism of S3M tiles and model objects in 3D scenes, improving the stereoscopic effect and detail representation of the scene. This technology is only available in the 3D Scene Rendering Engine V2.

Function Entry

  • Scene tab->Properties group->scene properties button->scene properties panel->Aftertreatment option->SSAO module

Operation Steps

  1. Open an existing scene or a new scene, click the Scene tab->Properties group->scene properties button, and the popped-up scene properties panel will appear.
  2. In the Aftertreatment option, locate the SSAO module, and set specific parameter values as needed to achieve the desired lighting effect.
    • SSAO: Control whether to enable SSAO by checking the checkbox, default is unchecked.
    • Intensity: Set the screen-space SSAO intensity, range is [0,2], default value is 1. Intensity can be used to control the brightness of the occlusion shadows, determining the depth of shadows produced when ambient light is blocked.
      • A higher value enhances the AO effect, making dark shadows more pronounced and improving the depth and layering of the image.
    • Radius: Set the screen-space SSAO radius, range is [0,20], default value is 10. Radius can be used to control the elements affecting the occlusion factor, thus adjusting the spatial range of the SSAO effect.
      • A smaller radius concentrates the SSAO effect in a smaller area, suitable for indoor small scenes and high-precision models.
      • A larger radius extends the SSAO effect to larger areas but may reduce computational efficiency and cause visual distortion, suitable for open worlds and large-scale environments.
    • Visible Distance: Set the screen-space SSAO visible distance, range is [0,20000], unit is meters, default value is 8000. Visible distance can be used to control the range where the SSAO effect is applied. Beyond the specified visible distance, the AO effect disappears.
  3. By clicking the reset defaults button, you can reset the adjusted parameters to the system default values.
