To start off: you should have a texture along with a bump map and a normal map for it. If you don't have a normal map for your texture, you can make one with Gimp and this filter For example: A texture named texture.jpg and a normalmap named textureNormal.jpg
Create your own texture folder within packages. So, packages/(name here). Add those textures in. Now, open up notepad, and type this:
setshader bumpparallaxworld
texture 0 "(name here)/texture.jpg"
texture n "(name here)/textureNormal.jpg"
texture z "(name here)/textureBump.jpg"
The first line tells Sandbox what shader to use. You might think about using the bumpworld shader instead; that's for just bumpmaps, not normal maps. I made that mistake as well, and always wondered why my textures didn't look right. The second line tells the engine what diffuse (color) texture to use. Lines 3 and 4 tell the engine what normal and bump maps to use respectively. Save the file as package.cfg, and save it within your new folder.
Now, go to either data/defaultmapsettings.cfg or (mapname)-art.cfg and add the line
exec packages/(name here)/package.cfg
This tells the engine to execute the commands within package.cfg, which adds the new texture to either all new maps, or just the map you chose.
That's it.
