For whatever reason, the program had the cobblestone pattern going one way to the left of the canal that the Bridge of Sighs spans and another way on the right side. I could not rotate the pattern to the right until I split it off from the one on the left and rotated it. I gave both the same properties, but for whatever reason the texture on the left ends up much darker than the pattern on the right. I am using Version 18 of A:M. I am also interested in knowing if there is a control for darkness
