Caw FAQ's........Links to Tutorials, and Resources. Textures, & Troubleshooting

In the Terrain textures links is a short tut on how to alter the textures you already have with gimp. I don't know how to save it correctly with other paint programs, so if you can't download gimp, which is also free, I don't know what to tell you.

Just out of curiosity, why are you unable to download these things? I can understand if it's someone else's PC. My Brother-in-Law won't let my Niece download anything onto their family computer. It seems odd that your computer won't let you, I'd be happy to try and help you figure out how to do it. :-)
