==> How to make his own Sidewalk ModRequested material : - SimCity 4 Rush hour or Deluxe
-
SC4Tool (clic here for download)- A 128x128 sidewalk texture ( .bmp recommended )
So, we start : You need a .dat file with some textures.
If you have already one, go to point 4) 
!
If you don't have one, take one in your plugins folder, I counsel you one with some textures, copy it with an other name (for exemple ; "my own textures" ) and put it onto a "zzzz" folder in your plugins.
Here we go :1) Open SC4tool and choose "texture editor"

2) Open your .dat file

3) We are going to delete all the textures in this folder, so you can add yours. Choose one per one all the textures and delete them with the cross button.
/!\ Warning, make sure that one texture rest here /!\
4) Click on «add a texture»

5) That window will appear, follow these step :
1. Tick on texture trafic
2. Use this button to choose your sidewalk textures.
3. Click on the little camera, that will resize the texture.
4. Tick the ignore box, for put your IID texture.
5. Here enter this IID : 0x08100000
6. Click Ok

6) Redone these step but with these IID : 0x08200000 and 0x08300000, that will give you three textures.
7) You can delete the textures of step 3
8) Quit SC4tool and start the game, good game !!
