Can somebody explain to me what is the difference between a paintmap and a wetmap? I'm currently studying dynamic painting and wondering the difference between these two outputs.

When a brush with a Color and a Wetness moves through a canvas, it lays paint.

As a result, the canvas gets

  • a color, represented by the (RGBA) Paintmap, and affected, for instance, by the Dissolve effect

    enter image description here

    (no dissolve in this example)

  • some wetness, represented by the (greyscale) Wetmap, and affected, for instance, by the Dry effect.

    enter image description here

Once the paint dries out (if it does), its color remains while its wetness goes away.

Example shader where the color is the paintmap, the specularity is the wetmap, the roughness is one minus the wetmap (there is also some alpha-based bump here):
