This section of the wiki is also extremely helpful when starting out with mapping. It can walk you through the basic (and more advanced) theories of mapping.

THANK YOU THANK YOU I MENT TO LET YOU GUYS KNOW I FOUND OUT WHAT IT WAS AS WE SPEAK IM MAKING A MAP. But, there is on more question on my mind.I see maps in dod:s with like a road made out of dirt then right off to the side of the road is grass how do you blend something like that???

the actual tire tracks are from an overlay, called dirttrack01a (and 01b, which is the end of the tracks). Search for it in the texture browser.

Otherwise, the blend between dirt and grass (or grass and rock, etc) is from Alpha channels on the displacement. Most of the textures that allow blending start with "blend". Once on a displacement, you can paint the alpha (the other texture, basically) using the texture tool.

see the last section on the bottom of this page for more about blending:

there is a list of tutorials from the DOD Federation. It should cover just about everything. If its not there its PROBABLY in the WIKI. DOD:F will probably be your best source for everything from content, to information, to testing.
