Here you can input the image or color from which an average color should be calculated. As a rule you will combine this input with a Mask Area in order to define the area of the texture tile from which the colors were extracted.
In order to also be alble to work quickly with high-res textures or resolution-free node calculations, the Color and Mask Area inputs will be baked to a reduced resolution prior to the actual node calculation. The Width and Height settings define the baking resolution. Higher resolutions will evaluate correspondingly more variations of the original image or pre-calculated node. However, the calculaton time for the node will also increase correspondingly.
Here you can apply values between 0% and 100% or grayscales. The Mask Area will be multiplied by the values at the Color input. This way you can use brighter grayscales to marke the areas of the Color from which the color for the average calculation should be extracted. Black masked areas will not be included in the calculation.
