Notes:

• Mask is only applied to the input texture.
• If background texture size is prioritized to be the size of the output texture.

Blur

Blurs the input texture.

Parameters	Description
Size	The target resolution size. This is used to reduce artifacts around the edges by blurring bigger input textures.
Mode	Blur mode specifies how pixels are taken into account in blurring. 3x3 is the lightest, while 7x7 is the heaviest.
Uniform Radius	Apply uniform radius (force y-radius to equal x-radius).
Radius	The radius of the blur for each axis.
Rotation	The rotation of the blur.
Num Passes	The number of passes to smoothen the blur result. Note that the performance gets heavier with more passes.

Coherent Noise

Parameters	Description
Noise Type	The type of noise: fractal, cylinders or spheres. The fractal noise is of brownian motion type. Cylinder noise is sin(uv.x) and sphere noise is sin(length(uv)).
Octaves	How many times to sample the fractal noise. Each additional sample is applied with 50% of the previous sample, at 2x the scale of the previous sample.
Scale	This changes the zoom level of the noise, which could also be called the frequency of the noise.
Offset	A position vector where sampling of the noise will begin. Use this as a seed parameter, or to scroll across the noise.
Absolute	If checked, this uses the absolute value of the noise sample. For the sine wave noises (cylinders and spheres) which range from -1 to +1, the formula is abs(sample). For fractal noise, which range from 0 to 1, the formula is abs(lerp(-1, 1, sample)).
Bias	Shift the noise value by a fixed amount. (sample + bias)
Invert	Inverts the value. (1 - sample)
Stretch	Modifies the sampling distance coordinate (uv.x * stretch) to stretch or compress the noise output texture.

Parameters	Description
Bg Color	The output color of pixels that don't pass the test.
Bg Depth	The output color depth of pixels that don't pass the test.
Invert	Inverts the depth test result.
