The Lines generator function draws randomly distributed horizontal and vertical lines along the texture's axis.

Use the Dimensions switch to control whether horizontal, vertical or both sorts of lines should be drawn.

The Elements Count value defines the number of lines, the Size parameter their average radius (i.e. half thickness) in relation to the texture's dimensions.

Make use of the Amplify value to change the contrast of the lines. Set the parameter to a greater value to remove the line gradient (Image 3).
