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.
Blurs pixels in a texture by using a Gaussian function.
You can use this to reduce color detail or noise in a texture.
Reduces the amount of color in the specified color.
As color is removed, the color value approaches its gray-scale equivalent.
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.
Sharpens a texture.
You can use this to highlight fine details in a texture.
