Picture of How to edit materials in any source game.
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
Also:
First instructable!

Feedback is lovely!
Please rate and comment!

Step 1: You need programs.

Picture of 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.

"I use mspaint, but photoshop is probably better."
Probably? lmao

Anyway, nice instructable, well written.
Hopefully it gets a few people into skinning.
dude- you have to use a program that recognizes transparency: MS paint doesn't
do that.

There is no 'Steam' folder in my Program Files. ?
it might be program files / 86 or something like that
Kirbsome! (author)  YouDucks324 years ago
What operating system do you use? On Windows 7 64bit, it's in
C:/Program Files (x86)/Steam. I'll add this to the instructable now.
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.

When I use GCFScape I navigate to SteamApps but nothing appears. No blue boxes.

Can someone help please? I have portal but there's no portal content. Can someone help?
Kirbsome! (author)  Galore43061 year ago
Have you installed, and played the game via steam?

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..
THANKS!
Kirbsome! (author)  megadarkwood3 years ago
I'm guessing you mean the mobility gels from portal 2?
.avi is a video format. All in-game textures are in .vtf (and possibly .tga) format.
You'd probably be better off just recording the game with fraps or something.

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?
Kirbsome! (author)  GLaDOS V33 years ago
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?
Kirbsome! (author)  GLaDOS V33 years ago
What?
I just said I don't even know how the Source engine works on 360.
Now you're asking me about all the other games?
GLaDOS V33 years ago
what file is that?
Kirbsome! (author)  GLaDOS V33 years ago
If you mean the Weighted Companion Cube, it's located in
materials/models/props/metal_box_skin001.vtf

Can you do this in mine craft
Kirbsome! (author)  Spencer . D4 years ago
Actually, it's much easier in minecraft. In the minecraft.jar file it's just a plain PNG file. There are plenty of tutorials on making "texture packs", just google it.
