Creates a field of spots that can be distorted and animated. The Warp Speed parameter causes the spots to be distorted over time by a random warping pattern.

In the Sapphire Render effects submenu.


Background:  The current layer.   The clip to combine the texture image with. This may be ignored if the Combine option is set to Texture Only.


Frequency:   Default: 8,  Range: 0.01 or greater.
The spatial frequency of the texture. Increase to zoom out, decrease to zoom in.

Radius:   Default: 1,  Range: 0 to 2.
The radius of the spots. Adjust this to change the size of the spots without changing the number of spots.

Seed:   Default: 0.23,  Range: 0 or greater.
Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

Rand Warp Amp:   Default: 0.2,  Range: 0 or greater.
The amplitude of a bubble warping distortion applied to the spots.

Rand Warp Freq:   Default: 1,  Range: 0.01 or greater.
The spatial frequency of the noise used for the warping distortion. This has no effect unless Rand Warp Amp is positive.

Shift:   X & Y,   Default: [360 243],  Range: any.
Translation offset of the texture. Since the texture is procedurally generated it can be shifted with no repeating units or seams occurring.

Warp Start:   X & Y,   Default: [0 0],  Range: any.
The translation offset warping pattern. This has no effect unless Rand Warp Amp is positive.

Warp Speed:   X & Y,   Default: [180 0],  Range: any.
The translation speed of the warping pattern. If non-zero the spots are animated to wiggle at this rate. This has no effect unless Rand Warp Amp is positive.

Brightness1:   Default: 1,  Range: 0 or greater.
Scales the brightness of Color1. Increase for more contrast.

Color1:   Default rgb: [1 1 1].
The color of the 'brighter' parts of the texture. The colors of the result are determined by an interpolation between Color0 and Color1.

Color0:   Default rgb: [0 0 0].
The color of the 'darker' parts of the texture.

Offset0:   Default: 0,  Range: any.
Adds this value to color0. Decrease to a negative value for more contrast.

Invert:   Check-box,  Default: off.
If enabled, the resulting texture colors are inverted. This is similar to swapping Color0 and Color1.

Bg Brightness:   Default: 1,  Range: 0 or greater.
The background brightness is scaled by this value before being combined with the texture.

Combine:   Popup menu,  Default: Texture Only.
Determines how the texture is combined with the Background.
Texture Only:  gives only the texture image with no Background.
Mult:  the texture is multiplied by the Background.
Add:  the texture is added to the Background.
Screen:  the texture is blended with the Background using a screen operation.
Difference:  the result is the difference between the texture and Background.
Overlay:  the texture is combined with the Background using an overlay function.

Input Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.
All Opaque:  Use this option to render slightly faster when the input image is fully opaque with no transparency (alpha=1).
Normal:  Process opacity normally.
As Premult:  Process as if the image is already in premultiplied form (colors have been scaled by opacity). This option also renders slightly faster than Normal mode, but the results will also be in premultiplied form, which is sometimes less correct.

Output Opacity:   Popup menu,  Default: Copy From Input.
Determines the opacity/transparency of the result. This effect does not process the opacity (alpha channel) of its input but it can either copy the opacity from the input, or output a fully opaque result.
All Opaque:  Makes the result fully opaque with no transparency.
Copy From Input:  Copies the opacity/transparency from the current layer given to this effect.
