Graffiti

To set up a custom spray in CS 1.6, put the spray image file (typically .bmp) into your cstrike folder. After that, open the game and navigate to Options → Multiplayer → Customize. Choose Import Spray and pick your file. The spray will be stored as tempdecal.wad inside the cstrike folder.

The spray file can go anywhere, but placing it in the cstrike folder is handy. The game won't load sprays from a folder automatically; you have to import them using the in-game menu. If you have a .wad file for map decals, put it in the cstrike folder.

Once you've imported your spray, join a game and point at a wall. Hit the spray key (by default T) to place the graffiti. You can reassign the spray key in Options → Keyboard.

If your spray fails, try these checks:

• Verify the image is a proper .bmp file.
• Confirm you imported it correctly through the Customize menu.
• Certain servers block custom sprays; test on a local server or one that permits them.
• If the spray shows up as a pink/black checkerboard, the file might be damaged or in an incorrect format.

To delete your custom spray and return to the default, remove the tempdecal.wad file from your cstrike folder. Then restart the game. The default spray will be restored.

That depends on the server. Many servers permit custom sprays, but some turn them off or substitute their own. If the server runs consistency checks, your spray might be replaced or you could be kicked. Review the server rules or test spraying on a local server first.

CS:GO graffiti aren't directly compatible with CS 1.6. CS:GO uses a separate graffiti system, whereas CS 1.6 uses sprays. You'd need to convert the CS:GO graffiti image to a .bmp file and import it as a spray in CS 1.6.
