This is a set of highly functional wall overlays devoted to architecture. I've had a number of things like this in my game over the years but this is the first set that meets my standards.
It's single sided and flat. you either see it or you don't. No weird floating edges.
It's not select able, there is no view interaction. it will not get in the way of your play.
It's has a diagonal state. It can be placed on diagonal walls and still tile perfectly.
It comes in several widths to accommodate windows, doors and wall edges. These smaller sections also tile in almost any configuration.
They are super Maxis match. Yay! They also fit perfectly with my standardized moldings sets. Those are in this post with more to be released... maybe.
