Field Pyro Material
Method #
A 3D field material suitable for pyro / explosions. The field density is used to control absorption and scattering, and the temperature of the field is used via black body simulation to output an emissive colour. The Scattering parameter is used to control the ratio of scattering vs 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 Colour
Controls the ratio of scattering vs absorption per colour channel.
Scattering
The ratio of scattering vs absorption.
Temperature Limits
If enabled, the temperature min and max values are used. otherwise the values from the field 3d root are used.
- Use root temperature : Conform to the temperature limits set by the root.
- Override : Override the root temperature limits.
Flame Emissiveness
Scales the emissive output.
Min Flame Temperature
The threshold above which the temperature contributes emissiveness.
Min Temperature (K)
The minimum temperature of the field for black body simulation, in degrees kelvin.
Min Temperature (K)
The maximum temperature of the field for black body simulation, in degrees kelvin.
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.
