How to change the floor texture

Question: How to change the floor texture?

Answer:

In the 'Edit Set /Location Parameters' dialog box, click the [Select New Floor Texture] button. A "Select Texture" dialog box appears.
Double-click the folder labeled "flooring" to view textures such as title and stones, or the folder "locations" for images such as simplified streets or grassy parks.
Select the desired flooring: for example "marble chessboard." A preview of the texture appears in the space to the right.
Click the [Open button, and you're returned to the Set Parameters dialog box.
