Volume Shaders - Arnold for Cinema4d

Volume shaders allow you to visualize a 3D scalar data field (e.g. density field) by sampling field values and mapping to color and opacity. You can assign volume shaders to volume shapes (e.g. Arnold Volume object or Turbulence FD container).

Atmosphere shaders are special volume shaders to simulate a light scattering effect in the scene, like fog. Atmosphere shaders have to be set in Arnold Render settings > Main > Environment > Atmosphere field.

Below is a list of available volume shaders:

• standard_volume
• volume_sample_float
• volume_sample_rgb

Atmosphere Shaders

Below is a list of available atmosphere shaders:

• atmosphere_volume
• fog

Workflow

Atmophere shaders can be found can be found under Create > Arnold > Volume > Atmosphere in the Material Manager.

Once you have created the material, drag it onto the Atmosphere attribute in the Environment section of the Main Arnold Renderer settings.
