S_DustGenerates random dust particles that move around the screen. Particles can vary in brightness and color, can move in different directions in a pseudo 3D space (making some appear bigger or smaller), and can flicker at different rates.In the Sapphire Render category.

-
Number Of Points:
Integer, Default:
200,
Range:
1 or greater.
Approximate number of dust particles to render. Particles may move off screen or move from the edges into view, but the average number of visible particles will stay consistent.
-
Size:
Default:
3.12,
Range:
0 or greater.
Scales the size of all dust particles.
-
Brightness:
Default:
0.75,
Range:
0 or greater.
Scales the brightness of the result.
-
Color:
Default rgb:
[0.5 0.5 0.5].
The overall color of the dust particles.
-
Vary Hue:
Default:
0,
Range:
0 to 1.
Randomly varies the hue of each dust particle.
-
Vary Saturation:
Default:
0,
Range:
0 to 1.
Randomly varies the saturation of each dust particle.
-
Vary Brightness:
Default:
0.5,
Range:
0 to 1.
Randomly varies the brightness of each dust particle.
-
Softness:
Default:
0.1,
Range:
0 or greater.
Softens the edges of dust particles.
-
Near Plane:
Default:
30,
Range:
0 or greater.
Determines the smallest distance away from the "camera" where dust particles can exist. If Box Depth is not zero, setting this to a lower value will make some particles appear closer (bigger) than the rest, whereas setting this to a higher value will lower the size differences between particles.
-
Box Depth:
Default:
500,
Range:
0 or greater.
Determines how far from the "camera" dust particles can exist. Setting this to a bigger value will make most particles appear farther (smaller), whereas setting this to zero will make all particles appear to be at the same distance (and so appear the same size).
-
Field Of View:
Default:
90,
Range:
0 to 179.
Simulates a field of view for the "camera", introducing a parallax effect where dust particles that appear closer will also move faster. Setting this to a higher value will bring more of the closest particles off screen, but most particles will still be visible.
-
Near Plane Fade:
Default:
20,
Range:
0 to 100.
Adjusts the brightness of dust particles that are too close to the near plane, such that they fade out instead of suddenly disappearing. This value adjusts the maximum distance to the near plane where particles start fading out.
-
Seed:
Default:
0.125,
Range:
0 or greater.
Initializes the random number generator for dust particle positioning, motion, size, color, and flicker variation. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.
-
Scale Drift:
Default:
2,
Range:
0 or greater.
Scales the overall non-turbulent motion of dust particles.
-
Drift Speed:
Default:
30,
Range:
0 or greater.
Determines how fast dust particles move in directions parallel to the screen (does not affect their distance to the "camera").
-
Vary Drift Speed:
Default:
10,
Range:
0 or greater.
Controls the variation in speed of dust particles (parallel to the screen, like Drift Speed). Setting this to twice the drift speed will make some particles not move (assuming no turbulence) and make some particles move at twice the average speed.
-
Drift Angle:
Default:
0,
Range:
0 to 360.
Determines the average direction of dust particles, parallel to the screen. A value of 0 or 360 means "toward the right", and the angle value goes counterclockwise.
-
Vary Drift Angle:
Default:
20,
Range:
0 to 360.
Controls the variation in the direction of dust particles (parallel to the screen, like Drift Angle). Setting this to zero makes all particles go in the same direction, whereas setting this to 360 makes particles go in completely random directions (which means the value of Drift Angle has no effect).
-
Drift Z:
Default:
0,
Range:
any.
Determines how fast dust particles move in the Z direction, that is away from (positive value) or toward (negative value) the "camera".
-
Vary Drift Z:
Default:
0,
Range:
any.
Controls the variation in speed of dust particles in the Z direction (perpendicular to the screen, like Drift Z).
-
Scale Turbulence:
Default:
10,
Range:
0 or greater.
Scales the overall turbulent motion of dust particles.
-
Turbulence Speed:
Default:
0.2,
Range:
any.
Controls how noisy the turbulence is. Without non-turbulent motion, controls the overall speed of dust particles (how fast the turbulent flow is).
-
Turbulence X:
Default:
25,
Range:
0 or greater.
Scales the turbulent motion in the X direction.
-
Vary Turbulence X:
Default:
15,
Range:
0 or greater.
Controls how noisy the turbulence is in the X direction.
-
Turbulence Y:
Default:
25,
Range:
0 or greater.
Scales the turbulent motion in the Y direction.
-
Vary Turbulence Y:
Default:
15,
Range:
0 or greater.
Controls how noisy the turbulence is in the Y direction.
-
Turbulence Z:
Default:
0,
Range:
0 or greater.
Scales the turbulent motion in the Z direction.
-
Vary Turbulence Z:
Default:
5,
Range:
0 or greater.
Controls how noisy the turbulence is in the Z direction.
-
Turb Octaves:
Integer, Default:
2,
Range:
1 to 10.
Controls the amount of detail in the turbulence noise.
-
Flicker Amp:
Default:
0,
Range:
0 or greater.
Controls the amount of variation in the brightness of dust particles that flickering can produce.
-
Flicker Speed:
Default:
40,
Range:
0 or greater.
Determines how fast dust particles flicker.
-
Flicker Randomness:
Default:
0.5,
Range:
0 to 1.
Determines how correlated the flicker of each dust particle is with its neighbors. A value of zero means that all particles flicker in unison, whereas a value of 1 means each particle flickers independently from all others.
-
Flicker Octaves:
Integer, Default:
2,
Range:
1 to 10.
Determines how random the flickering pattern is (the amount of detail).
-
Coverage Percent:
Default:
30,
Range:
0 to 100.
Determines how many dust particles flicker. This is a percentage, so a value of 0 means none of the particles flicker, whereas a value of 100 means all particles flicker. Which particles flicker is determined randomly, but using a mask can help control in which regions the particles flicker.
-
Depth Blur Amount:
Default:
0,
Range:
0 or greater.
Blurs dust particles depending on the focus depth and depth of field. The farther from the focus depth (in the Z direction) a particle is, the more blurred it gets.
-
Focus Depth:
Default:
50,
Range:
0 to 100.
Sets the Z position of a plane of focus where all dust particles are in focus. This is expressed as a percentage of Box Depth, so if that value is zero, then the value of Focus Depth does not matter. A value of zero makes the plane coincide with the near plane.
-
Depth Of Field:
Default:
10,
Range:
0 to 100.
Introduces an interval centered on Focus Depth where dust particles stay in focus.
-
