Converting .map into .bsp

I have been caught up in a dilemma trying to get .map files to work on Half Life Multiplayer Deathmatch, ofcourse the map files for multiplayer is .bsp but how could I change it to .bsp so it works?

.map contains the map in a format ready to be compiled, .bsp contains compiled data, so you'll need to compile your .map file. Easiest way is to set up Hammer (there are some tutorials on this site) and load up the map.

Make sure there are no problems (Alt+P), especially that no textures appear white, which means you have missing .wad files (texture files). If you do, find out the texture name that's missing and google it, if you're lucky you'll find the wad name.

Finally, compile the map. If you want it done easily with bad quality, do it in Hammer and if the compile succeeded the .bsp should appear in your game folder. For better quality, use something like HLCC+ZHLT and read up on the best parameters to choose. Again, there are tutorials on these.

Yeah, you need to compile your map which produces a bsp file from a map file. There is heaps of documentation and a few different ways to compile a map.

You need compile tools, either the old Q tools that valve made or the better and updated ZHLT tools.

Once you have the tools, you can either:

1) Configure Hammer with the tools so you can compile the map in Hammer by pressung [F9]

2) Use a batch compiler.

3) Write your own simple bat file.

But how do I compile in Valve Hammer? Or do I need VHE 3.5?

Any Hammer can compile, I use Hammer 3.4 for HL1 games. Set up Hammer according to http://www.snarkpit.net/index.php?s=articles&article=53 and press F9 to compile. Put CSG, BSP and VIS on Normal and turn RAD off, compile and test. If the map looks fine apart from being full brightness, recompile with RAD on Normal/Extra.
