UMaterialExpressionNoise

Whether to use tiling noise pattern, useful for baking to seam-free repeating textures

How multiple frequencies are getting combined

Scalar, to clamp the Levels at pixel level, can be computed like this: max(length(ddx(Position)), length(ddy(Position))

1 = fast but little detail, .. larger numbers cost more performance

Usually 2 but higher values allow efficient use of few levels

Noise function, affects performance and look

2 to 3 dimensional vector

Lower numbers are faster and lower quality, higher numbers are slower and higher quality

How many units in each tile (if Tiling is on)

Can also be done with a multiply on the Position

Create the new shader code chunk needed for the Abs expression

Returns the text to display on the material expression (in the material editor).

Called by the editor to query whether a property of this object is allowed to be modified.
