The Scene Settings panel allows you edit certain properties of an entire scene, such as the skybox, global illumination, background sound, and media surface settings.

Skybox settings

Skybox settings.

These settings define the scene's skybox, the texture that is used to represent the sky in your scene. You can adjust the following settings:

  • Skybox - Choose from one of the predefined skybox textures, or pick one that you have uploaded in .exr format.
  • Sky Brightness - Move this slider to increase or decrease the brightness of the entire sky.
  • Sky Rotation - Enter X, Y, and Z values in degrees (from 0.0 to 360.0) to rotate the skybox texture along X, Y, and Z axes.

Atmospherics settings

Atmospherics settings and the Color panel.

These settings define the look of the atmosphere in a scene:

  • Fog color - Defines the color of atmospheric fog in the scene. Provide values from 0-255 for Red, Green, and Blue or click the dropper icon to open the Color panel and choose a color from the palette.
  • Fog Scattering - Affects the direction that light is scattered when looking at a light. At low values, an "aura" can be seen around light sources and fog farther away seems darker.  At high values there is no halo around light sources and the fog seems more uniformly lit.
  • Ground Fog Falloff - Adjusts the rate at which the fog density decreases with altitude.
  • Ground Fog Density - Adjusts the overall density of fog in the scene.  Set this to zero in order to disable fog in the scene.
  • Sky Distance - Set the simulated height of the skybox for atmospheric scattering purposes; lower values cause atmospheric scattering to show more of the sky's color.

Exposure settings

Exposure settings.

Exposure settings allow you to adjust how bright or dark your scene appears:

  • Exposure Bias - Adjust between -2.0 and 2.0 (corresponding to photographic f-number) to darken or brighten your scene, respectively.
  • Underexposure Adapt - Affects how much the scene is allowed to compensate when looking at an area that is too dark. Higher values allow for increased brightness in dark areas.
  • Overexposure Adapt - Affects how much the scene can compensate for overly bright areas. Higher values increase the amount the scene dims when viewing something brightly lit.

Light settings

Global illumination quality settings.

There is currently only one property under Light settings: Global Illum Quality. For more information, see Global illumination.

Sound settings

Sounds settings.

Sound settings let you set and adjust a background sound for the whole scene and choose whether or not to compute reverb on sounds in the scene.

  • Background Sound - Choose a sound you have uploaded to Sansar. The sound is played in a loop while visiting the scene. You can preview the looping sound while editing the scene by clicking Options and enabling Audio Preview.
  • Background Level dB - Increase or decrease the volume of the looping background sound, measured in decibels (dB).
  • Compute Reverb - Enable to allow the scene to simulate realistic reverb based on objects and materials in the scene. For full information, see Compute Reverb.

Media surface settings

Media surface settings.

Media surface settings allow you to customize web content playback in your scene. For details on how to use these settings, see Media surfaces.
