Six world, wall, and terrain textures (Base Game) made available as floor tiles: the grey cobblestone, three stone walls, and two brick patterns.
The cobblestone is available in two different sizes (the smaller one is the same scale as the terrain paint it is from). All of them are in the Outdoor floor category; the cobblestones are also in Masonry and the rest in Stone. The bricks are in the same thumbnail as the “Academia Brick Paver” (shown on the left of the brick screenshot for comparison). Note that they do not have bumpmaps, so they look a little less 3D than the Academia one.
All textures are referenced directly.
