Example II
This is a slightly more complicated iteration of Example I. It uses a very similar layout however the alpha for the Lerp is controlled via EXTILE's procedural splat mask function and a there is an additional procedural puddle effect added.
NOTE: EXTILE comes with a Master Material that can break up repetitiveness on a lot of types of textures. The usage of the material functions as shown in these examples - that come with the project are optional and are only there to enhance your material creations should you wish.
