V-Ray Layered texture offers stacking of multiple textures on top of each other in order to mix their output. The result of each layer depends on the blending mode with the next layer in the stack. You can also use a mask to control what parts of the texture will appear in the render.
Note that the "upper" layer is the one with higher number. That is, Layer[0] is the bottom layer.

When adding a new layer, it is placed on the bottom of the stack. Layers are applied from the top to the bottom.
