I hope this question isn't too noobish, but I'm trying to make character skins and am having a problem with file conversion. Before you ask, yes I have downloaded and read several tutorials on this, I also have the necessary "dds to iwi" and vice versa programs as well as all the PS plugins. I've opened iw_08.iwd and have looked for the files I'm trying to edit. All of the extensions are in a .gsc format and I need to get them to .iwi before I convert them to a dds. I tried simply renaming/resaving the .gsc file as an .iwi, this appears to work but then the iwi to dds program will convert the file into a .dds, which shows up as blank in Photoshop. I've searched several forums for a few hours for help, the only time I've seen this problem addressed is this post here: http://forums.filefront.com/showthread.php?t=252354 But the guy figured it out on his own and never posted a solution. Can anyone help me? Am I converting the file wrong? Am I looking in the wrong place for .iwi files? Thanks for any info.
I haven't found the right way to convert .gsc to .iwi. Just like you. Perhaps we should contact the guy who found the solution.
I think i may have found an answer. In the iw_08.iwd file, there's a folder conveniently named "characters," with files in it named "american_normandy.gsc" for example. I assumed that these were the files to edit for a skin. These are actually the individual character skins from single player. Guys like Braeburn and the colonel, etc. If you look in the images folder in the iw_08.iwd file, there are more generic skins, such as "american_rangers.iwi" for example. Since this is the appropriate iwi file format, I think these are the ones to edit. Keep in mind that the image folders start in iw_08.iwd and can be found in every folder after that. Each image file is located in the folders alphabetically, which causes most of the weapon files to be found in iw_09.iwd, not _08. I hope that helped anyone else with the same problem. I just finished the US ranger and M1 garand skin and am going to test them out now. Hopefully they'll work.
This is all about as wrong as you can get.
An IWI file is an image file - a form of "super" DDS file
A .gsc file is a compurter language file - a 'text' file. You cannot convert a .gsc file to an IWI file as it isnt an image file.
All IWI files are in folders called "images" (from iw_08.iwd > iw_13.iwd) absolutely none are in the "characters" folder.
Didnt the fact that the .gsc files in "characters" not have the IWI file extension name alert you to this fact? If IW wanted a file to be an IWI file, it would be called an IWI file. If its not, it isnt! Its really that simple.
As for converting back and forth between IWI to DDS; DDS to IWI, you need to save your DDS file as a DXT5 with full mipmaps (in your DDS plugin, make sure there is a check in "generate mipmaps").
Ok, so I don't know what a .gsc file is for, but I did know that I was looking in the wrong folder for the skin files to edit. I thought I might have skipped a step in the conversion process, but I figured out on my own that it was my own damn fault for looking in the totally wrong folder. I found the files that I needed, there is no need to bother with any .gsc files in the skinning process. Once I had found the iwi files that I was looking for, it was smooth sailing after that.
