Filter Nodes

In the Shader Designer, filter nodes transform an input—for example, a color or texture sample—into a figurative color value. These figurative color values are commonly used in non-photorealistic rendering or as components in other visual effects.

Node	Details	Properties
Blur	Blurs pixels in a texture by using a Gaussian function. You can use this to reduce color detail or noise in a texture. Input: UV: float2 The coordinates of the texel to test. Output: Output: float4 The blurred color value.	Texture The texture register that's associated with the sampler that's used during blurring.
Desaturate	Reduces the amount of color in the specified color. As color is removed, the color value approaches its gray-scale equivalent. Input: RGB: float3 The color to desaturate. Percent: float The percent of color to remove, expressed as a normalized value in the range [0, 1]. Output: Output: float3 The desaturated color.	Luminance The weights that are given to the red, green, and blue color components.
Edge Detection	Detects edges in a texture by using a Canny edge detector. Edge pixels are output as white; non-edge pixels are output as black. You can use this to identify edges in a texture so that you can use additional effects to treat edge pixels. Input: UV: float2 The coordinates of the texel to test. Output: Output: float4 White if the texel is on an edge; otherwise, black.	Texture The texture register that's associated with the sampler that's used during edge detection.
Sharpen	Sharpens a texture. You can use this to highlight fine details in a texture. Input: UV: float2 The coordinates of the texel to test. Output: Output: float4 The blurred color value.	Texture The texture register that's associated with the sampler that's used during sharpening.
