Field Cloud Material
Method #
A 3D field material suitable for smoke and cloud volumes, which shades solely based on density. The Scattering parameter is used to control the ratio of scattering vs absorption. Clouds have high scattering, low absorption; smoke has low scattering and high absorption.
Parameters
These properties control the core behaviours of the node.
Parameter Details Tint Colour
Tints the field.
Density
Scales the density of the field.
Scattering
The ratio of scattering vs absorption.
Scatter Mode
The method of scattering.
- Isotrophic : Uniform in all directions
- Anisotrophic : None uniform
Scatter Anisotrophy
How much none uniformity the scatting has.
Scattering Colour
Controls the ratio of scattering vs absorption per colour channel.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
Inputs
