Talk:List of useful Portal models

I'm making a Portal mod, and I want to make my own test chamber signs. How would I go about "altering" the models so that, say, I could add the flinging icon to the Test Chamber 01 sign, or add my own icons? —Yar Kramer 16:49, 17 Jan 2008 (PST)

Firstly, you shouldn't change any content inside the official GCFs (in this case, portal content.GCF). What you can do is open up that GCF file (using GCFScape or similar tool) to extract the models you wish to alter (in this case, one of the group of files inside "root\portal\models\props_animsigns"), and start by changing their file names (so they will not be loaded instead of the (original) ones in the GCF!!). Then, you can create your own files based on the ones you extracted. After doing so, be sure to place them in the correct folder (i.e., for the Test Chamber XX sign files, the folder would be "%SteamInstallDir%\Steam\SteamApps\portal\models\props_animsigns").

As to how you change the files themselves, you'll just have to read about it elsewhere here on the wiki, since it's out of my grasp of knowledge! Start by extracting the files and researching about their file types, that should give you enough information to understand what each file is, and how to edit/create it. --Etset 02:27, 18 Jan 2008 (PST)

Heh, yeah, I know how to get stuff out of the GCFs. It's just that, well, what I didn't know is, as you say, beyond your graps of knowledge. ;) —Yar Kramer 13:01, 18 Jan 2008 (PST)
