Each wall uses at least 2 textures, max 3 fade, the first of the materials intended for the sections of walls that fade out, used on all walls that don't have the "_NoFade" in their name, the second is intended for the walls sections that don't fade out and the final material is intended for the middle sections of the wall, the gaps between the inside and outside that should just use a generic blackish mat.
The strait walls have 3 fade sections, one intended for single walls with no adjacent walls the "edge" walls that are intended to be connected to an adjacent tile and the "middle" walls used where they have 2 or more adjacent wall tiles.
The UVs should line up however corners might require negative scaling and some walls might need rotating 180 to line up and some might need both. Should be fairly simple but a little time consuming.
