How To Use Tutorial:
First of all make sure you have all required files. "TextureEditor.exe" and "libsquish.dll" must be in the same folder. You also need to have a pak file to load. You can use PSARC Extractor tool to extract pak files from psarc archieves just google it and you will find it. Make sure you have a backup of your pak file in case you mess up. So for this tutorial I will use the pak file "ellie-jacket-cloth-snow.pak" which is extracted from actor34.psarc and it has the textures for Ellie's outfit in winter season. We open the TextureEditor.exe and we click "File" tab on top and we choose "Open.." and a window will pop up to choose our pak file. We choose our .pak file and click OK.
