If you've ever played a source game (hl2, css, portal), you have probably seen one or more materials that just wasn't good enough. It is also likely you have thought "What if i could edit this?" With these steps, you can!

note:
It doesn't have to be steam, as long as it has a .gcf library and uses the source engine

First instructable!

Feedback is lovely!
Please rate and comment!

Step 1: You need programs.

Neither can you find, nor can you edit the materials without any additional programs.
These are your saviors in that matter:

GCFscape:
A program used to open GCFs "Game Cache Files", which are actually folders containing all the games files.
Get it here:

VTFedit:
While browsing the gfc, this program is used to open VTFs "Valve Texture File" These are the materials and sprites used in your game of choice.

&quot;I use mspaint, but photoshop is probably better.&quot;<br /> Probably? lmao<br /> <br /> Anyway, nice instructable, well written.<br /> Hopefully it gets a few people into skinning. <br />
dude- you have to use a program that recognizes transparency: MS paint doesn't <br>do that.<br>
Thanks for the feedback!<br />
There is no 'Steam' folder in my Program Files. ?
it might be program files / 86 or something like that<br>
What operating system do you use? On Windows 7 64bit, it's in<br>C:/Program Files (x86)/Steam. I'll add this to the instructable now.<br>Also, if you're using a pirated game you might not even have steam.
It's a nice instructable, but I have one question. I'm editing the metal_box.vtf texture so that all cubes look like companion cubes, but I can't figure out where to save it to. I followed the destination and everything.<br />
...\portal\portal\materials\models\props<br />
I'M at <em>C:\Program Files\Steam\steamapps\bigbrainkid\portal\portal</em>, but there doesn't seem to be a <em>materials </em>folder.<br />
so make a new one<br />
<p>Found it, it's changed since this guide was made, the files are now in<br><br>Steam\steamapps\common\GarrysMod\garrysmod\garrysmod_dir.vpk</p>
<p>There are no such files in my steamapps..? Help? Btw, I'm also Swedish :3</p>
<p><strong>Help!</strong> I bought and downloaded Portal, installed it probably, but i can't find <em>Portal/Portal/Materials/Models/ </em>anywhere!?</p>
<p>I went to steamapps, but there is not a single thing exept for some folders!</p>
<p>Yeah, the guy who made this is a bit on the dumb side in terms of leading you to where you need to be.</p><p>Steam\steamapps\common\GAME\</p><p>From there, where-ever the files you need are stored.</p>
<p>Can somebody please help me. I do not seem to have any of the GCFs for any of my source games, but I have run them all multiple times and I acquired each game from Steam. Why do I not have them and how do I correct this problem? </p>
<p>dude after we have edited the jpg image what has to be done do we have to change it back into VTF or what </p>

<p>When I use GCFScape I navigate to SteamApps but nothing appears. No blue boxes.</p>
<p>Hello, i tried to create a skin for the portal gun, but I can't load it in my game like he doesn't exist. All of tutorial i see say you must create a folder 'materials' or 'custom', but still doesn't worked, so if you can help me with that :)</p><p>Have a nice day (sry for my bad english)</p>
<p>Did you save it in .VTF format?</p>
Can someone help please? I have portal but there's no portal content. Can someone help?
Have you installed, and played the game via steam? <br> <br>Did you actually buy the game?
Hey can you find me the jel and the jel dispenser from portal? and possibly an .avi or something? i want to use it for a movie. if you cant its ok.. <br />THANKS!
I'm guessing you mean the mobility gels from portal 2? <br>.avi is a video format. All in-game textures are in .vtf (and possibly .tga) format. <br>You'd probably be better off just recording the game with fraps or something. <br> <br>If you really want to find those files, look for them yourself. I don't mean to be rude or anything, just consider it a learning experience.
Yes and ok. Thanks for ur reply tho and sorry for my late one
How do I do this to The Orange Box for xbox 360? <br>
I have no idea. As far as I know, The Orange Box was ported to X360 by EA, and has loads of differences from the PC version.
could you do this on any xbox 360 game?
What?<br>I just said I don't even know how the Source engine works on 360.<br>Now you're asking me about all the other games?
what file is that?
If you mean the Weighted Companion Cube, it's located in<br>materials/models/props/metal_box_skin001.vtf
Garys mod rocks and who is that smily face guy

Can you do this in mine craft<br>
Actually, it's <em>much</em> easier in minecraft. In the minecraft.jar file it's just a plain PNG file. There are plenty of tutorials on making &quot;texture packs&quot;, just google it.<br>
that helps with my plans.also- to find your .minecraft file click on run in you thing that says windows &amp; type '%appdata%
how do i add my .vtf pic back to the game immmm sooooo confused but ur great maybe you can help<br>
You need to be more detailed be fore I can help you. Do you have the .VTF? Are you confused about where to put it? Is there a problem with exporting the file from VTFedit?
can you do this in need for speed undercover<br>
