S_Brush
Description
Simulates the look of an oil painting or a chalk drawing by layering brush strokes of different sizes and directions. This effect can be used with one of the following brushes: felt tip, splat, water color, stipple, pencil, pastel, sponge, splodge, round, or cubes.
The S_Brush filter comes from the Emmy award winning Boris FX Sapphire filter set.

Style
Brush Oil
Simulates the look of an oil painting by layering brush strokes of different sizes and directions.
Brush Chalk
Simulates the look of a chalk drawing by layering brush strokes of different sizes and directions.
Shape
The shape of the brush.
Match To Style
Use the brush shape that matches the current paint style. Round matches to Oil and Sponge matches to Chalk.
Felt Tip
An opaque, triangular shape.
Splat
A shape of sparsely packed fine dots.
Water Color
A coarse, blobby shape.
Stipple
A soft, rectangular shape with holes.
Pencil
A long, thin shape.
Pastel
A long, funnel shape, like a comet.
Sponge
A very coarse, rectangular shape.
Splodge
A soft, misty, rectangular shape.
Round
A soft oval shape with coarse trails, like a jellyfish.
Cubes
A square shape.
Max Size
Sets the maximum brush size. No brushes will be larger than this size.
Size Range
Scales the range of the brush sizes measured from the maximum brush size.
Angle
Rotates the orientation of the brushes.
Vary Angle
Randomly rotates the brushes up to this amount in one direction.
Contour Alignment
Interpolates between the brush stroke direction being fully aligned to the angle parameter (0) and the contours of the original source (1). Vary angle offsets of the stroke in both directions from this interpolated direction.
Layers
The number of layers to paint.
Density
Sets the overall density of brush strokes per layer.
Rel X Density
Scales the density of brush strokes in the X−direction.
Rel Y Density
Scales the density of brush strokes in the Y−direction.
Vary Position
Shifts the brush positions randomly in all directions. A value of zero places all the brushes on a regular grid.
Roughness
Scales the intensity of the highlights on the paint, similar to increasing the thickness of paint.
Intensity
Scales the saturation of the brush opacity, growing the perimeter of the brush.
Deterioration
Scales the shadows created by roughness, similar to cracking or peeling paint.
Smooth Colors
Blurs the source to smooth the color palette and help reduce some brush stroke jitter.
Use Source Color
Interpolates between the paint color parameter (0) and the original source color (1).
Paint Color
The paint color to use.
Bg Opacity
Scales the opacity of the background before combining with the brushes. If 0, the result will contain only the brush image over alpha.
Seed
Used to initialize the random number generator. The actual seed value is not significant, but different seeds produce different results and the same value should give a repeatable result.
Crop To Source Alpha
Crops the effect to the boundary of the source alpha.
Soft Borders
If enabled, transparent borders are added to the image before processing. This allows the result to include soft edges beyond the original image size. When off, the effect only occurs within the frame and the result will retain an edge at the borders.
