First I added a Landscape object. I set the landscape object to 40x40 division, since my maze is on a 20x20 grid. Then I aligned and sized the Landscape object over the image of the Maze.
I convert the Landscape object to a polygon object. Selected the polygon that is over the Maze image. I then used a Knife tool to slice along a plane to get the Walls. After that I select the polygon that would become the floor of the Maze and Extrude it downward. I extruded the Skirt of the Landscape object to hide the downward extrusion.
next I placed a random Effector object in to the scene and linked it with the Cloner object. To randomize the Rotation and Scale of the Landscape object inside the Cloner object.
I Textured the entire landscape with Crown Glass Texture. I then Selected out only the Floor of the Maze object and Texture it with a wood late like texture. I added a Background object to give me a sky. I used a Sky object with a Composite Tag to be invisible to the render but still reflect on the Glass texture to give it some Sheen. I also added a few landscape object to scene near edges to break up the straight Lines.
