Cloud Layer

A Cloud Layer is an object representing a layer of realistic volumetric clouds with convincing dynamics.

Unigine clouds offer the following features:

  • Simulation of multiple types of clouds: cirrus, stratus, cumulus, cumulonimbus, etc.
  • Local clouds coverage simulation (with the FieldWeather object) with the ability to control movement of numerous groups of clouds without performance drops.
  • Cloud dynamics simulation.
  • Cloud density simulation based on a 3D noise model.
  • Realistic shadows and lighting.
  • Large number of configurable cloud layer parameters (height, density, lighting, shadows, wind, etc.).
  • Visibility distance up to 400 km.

Several cloud layers can be used to provide realistic simulation.

Adding a Cloud Layer

To add a cloud layer to the scene via UnigineEditor:

  1. On the Menu bar, click Create -> Object -> Cloud Layer:

  2. Place the cloud layer object in the scene:

A layer of clouds will be added to the scene and you will be able to adjust it via the Nodes window.

Adjusting a Cloud Layer

Cloud layers have a realistic look with the default settings, so you might not need to tweak them at all. However, when necessary, you can adjust a large number of parameters to achieve the desired look of your cloud layer.

There are two ways of you can adjust the look of your clouds:

  • By using the corresponding Rendering Settings applied to all cloud layers in the scene.
  • By using the parameters of clouds_base material providing an opportunity to tweak each layer separately.
You can use several Cloud Layer objects each with its own material inherited form the clouds_base material.
