That is a tip by olve11 for which I created some illustrative pictures.

If we want to stack texture images we to work with a layered material and it's weight. But, if we don't want them mixed we must to use masks to ensure the proper overlapping. In this case we must to set a mask for each material Weighting which each layer mask must be combined with the previous one.



So, in the Material editor dialog we first select Layered material; then in the Weighting box we select one Weight #<n> and in the Texture Editor box we start to set the mask (2nd image with the process flow). Notice that the first block (top most) must be repeated for every Weight#<n> property:



In this sample I used .png images with alpha that are used as the mask - see the Alpha Channel property checked and inverted for every Weight# in image.

Because we want to mask the material we are going to use the "x" icon to 'Add mask layer'. This process will ensure we are able to stack as many material/textures as we want:
