Field Flame Material
Method #
A 3D field material suitable for fire / flames. 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 temperature is also used to control the opacity of smoke and flames: temperatures below the Smoke Max Visible Temperature value are rendered as smoke, temperatures above the Flame Visible Temperature value are rendered as flame.
The smoke and flame shading can be controlled separately with this material to some extent. The smoke opacity is controlled with the Smoke Density parameter. The flame opacity is controlled via the Flame Density parameter.
Parameters
Parameter Details Flame Density Scales the density/opacity of the flames.
Flame Emissiveness Scales the emissive output.
Flame Visible Temperature (Kelvin) The temperature threshold above which cells are rendered as flames.
Override Temperature Range If enabled, the temperature min and max values are used. otherwise the values from the field 3d root are used.
Temperature Min (Kelvin) The minimum temperature of the field for black body simulation, in degrees kelvin.
Temperature Max (Kelvin) The maximum temperature of the field for black body simulation, in degrees kelvin.
Smoke Density Scales the density/opacity of the smoke.
Smoke Tint Colour Tints the smoke.
Smoke Scatter Colour Controls the ratio of scattering vs absorption per colour channel for the smoke.
Smoke Scattering The ratio of scattering vs absorption for the smoke.
Smoke Max Visible Temperature (Kelvin) The temperature threshold below which cells are rendered as smoke.
