A billboards_cloud_base material is used to create independent small clouds via Billboards.

Clouds Billboards

Billboard clouds


In this tab you can set available settings and options:


Material Editor, billboards_cloud_base material, States tab.

  • Axis x - lock a billboard along X axis.
  • Axis z - lock a billboard along Z axis.
  • Screen - set billboards perpendicularly to each other.


Locks billboards orientation along X axis (by default billboards always face the camera).

Disabled axis_x
Enabled axis_x


Locks billboards orientation along Z axis (by default billboards always face the camera). Billboards can be also locked along both X and Z axes, so they will be oriented perpendicularly to Y axis.

Enabled axis_z
Enabled both axis_x and axis_z


Set billboards parallel to each other. If they are not axes-locked, they will be oriented strictly towards to the screen plane.

Disabled screen
Enabled screen


Soft interaction

Enables soft interaction for billboards and objects, so the interactions would not be sharp and cause artifacts.

Disabled Soft interaction
Enabled Soft interaction


In this tab you can choose textures for billboards:

Material editor, Textures tab.


Base textures:


This tab represents parameters available for the material. All of the parameters have set default values, which can be replaced by your own ones. Availability of some parameters can depend on the set States tab values.

Material editor, Parameters tab.

Transformation parameters:

  • Base - material coordinates transformation.

Other parameters:

  • Color 0 - main color of the cloud.
  • Color 1 - color of the cloud shadow.
  • Multiplier - diffuse texture intensity scale.
  • cloud_scattering - scattering value.
  • Distance - near clipping distance value.

Soft interaction parameters:

Color 0 and Color 1

Color pickers choosing the main color and the color for shadowed parts of the cloud.

An example of the cloud colors configuration:


A slider setting the scattering value for clouds. The higher the value the more visible the clouds are.

Scattering = 0.1
Scattering = 0.2
Scattering = 0.3


A slider setting the near clipping distance, starting with which billboards are rendered.

Soft Interaction

A slider setting interaction value for clouds. The higher the value, the closer to the object clouds are rendered.

Interaction = 10
Interaction = 40
Interaction = 100
A parameter is present only if a Soft interaction option is enabled.
