==Whats needed==
* [[MD3 Compiler|Npherno's MD3 compiler]]
* An MD3 model

==What's this about?==
This tutorial gets you acquainted with a useful and concise tool titled 'Npherno's MD3 Compiler', which can be used to alter MD3 models. More specifically, it shows you exactly how to set or change the material of a surface.

[[Darkplaces material system|Materialnames]] are stored in the MD3's themselves. When the game loads a model, it uses the embedded material name to load the proper material or texture.

Altering MD3's can be tricky at first, but it's rather easy and doesn't take more than half a minute at most.

==Step 1: Importing objects==
Launch the MD3 Compiler. It's the "MD3Compile.exe" file.
This is what you'll see:

Now, click the button labeled "Import objects", and select the MD3 you wish to alter.
It shows the following popup:

Select all parts of the model, and click "OK".
The model should now appear in the center as a red and blue set of objects.

The window should look something like pic 3.
{{important|Now, click the "All" button (located directly above "Import objects"). Make sure the checkbox in pic 4 is checked before you proceed!}}

==Step 2: Altering the material==
Now we can alter the material of any of the imported objects.
Usually, you'll find the MD3 only has one object. If you've selected more than one object in the import pop-up (see pic 2), there might be objects with a path need to be edited.

Use the top-most dropdown-list to select an object (in this case, we can see that w_nailgun has been selected). The embedded path to the skin will be shown in the field immediately below it. You can edit the path now. 
{{important|Remember to always use forward slashes in paths. No matter what the original path shows, use forward slashes. Failure to do so means you won't see a texture in-game.}}
{{tip|If you are change material to empty or malicious string (like ''<nowiki>%@#====6%$!!!!  ----</nowiki>'') it will not be drawn}}

==Step 3: Final step==
Once you've edited the paths of all objects, it's time to export the model, saving all of your changes.
Click "Export objects" and give the MD3 a nice name. You can overwrite the MD3 you imported without problems, by the way.

A popup will show, asking for an "Internal name". Unless you're editing a player model, ignore this - leave it blank.
Just click "OK".

That's all there is to it. 

==Recap==

# Import objects
# Alter name (remember, FORWARD slashes)
# Export objects
