Random rectangles drawer
This node draws a series of rectangles into a texture set. The rectangles are drawn in a 1-dimensional array pattern, vertical or horizontal, with space between each of them. Each 1D array is called a layer. The node can draw several layers at once. The rectangles don't necessarily have the same width in the same layer, nor the same spacing between them. Use the parameters to control that.
Example with three layers of rectangles
It can be used for example to add some visual variety to an otherwise monotonous image. For example it works great in combination with the simple windows drawer.
