Create a constant volume within a box to add atmosphere to your scene.
The scene graph path at which to create the fog box prim.
The density of the volume.
Specifies a scale on the density value used for shadow rays. You can only decrease the density for shadows to allow more light to propagate through the volume than would happen physically.
Specifies the Henyey-Greenstein phase. A value of 0 results in isotropic scattering.
The color of the light reflected from the smoke.
The number of samples to generate when rendering the volume. The samples will be distributed so as to produce an equal image contribution if they were all equal in brightness.
Movement amount along XYZ axes.
Degrees rotation around XYZ axes.
Non-uniform scaling along XYZ axes.
Uniform scaling along XYZ axes.
