To make all of your map textures tuirn grey you have to:
1. Go into your CA folder
2. Go to "Game"
3. Go to any "MAP" folder
4. Take out the TEXTURE folder ( NOT THE TEXTURE SCRIPTS!)
5. Start CA
6. Go in any map and have fun owning!
This is old... Everyone already knows how to do this...
Dont post something twice if it is already known.
