Planet Atmosphere


Overview[edit]

The Planet Atmosphere node provides all the effects of a full planetary atmosphere, including blue sky, the red of sunsets, and distance-enhancing haze. You can control many aspects of the atmosphere to fine-tune or enhance a realistic Earth-like atmosphere, or create completely alien skies. The default scene includes a Planet Atmosphere node. Note that clouds are created separately using the Add Cloud Layer button.

Settings:

  • Enable primary: Controls the visibility of the atmosphere itself, primarily manifested as haze. When enabled the camera directly sees the atmosphere, but when disabled causes the sky to become invisible to the camera. If Enable secondary is on, the atmosphere will still affect the lighting on any clouds and the terrain in the project.
  • Enable secondary: Responsible for the global illumination, reflections and shadows of the atmosphere. When enabled, shadows and reflections of the atmosphere are rendered. When disabled, they are not rendered, therefore the reddening of the light at sunset won’t be visible or the atmosphere on the dark side of a planet will still be fully lit because the shadows aren't calculated.
Primary and Secondary enabled.

A single object or device in the node network which generates or modifies data and may accept input data or create output data or both, depending on its function. Nodes usually have their own settings which control the data they create or how they modify data passing through them. Nodes are connected together in a network to perform work in a network-based user interface. In Terragen 2 nodes are connected together to describe a scene.
