Only .zip files supported.
This tool fixes the two main reasons your League mods break after patches:
1. File Naming:Riot sometimes renames files like "champion.pie_c_1_1.dds" to "champion.dds". This tool generates both versions so your mods stay compatible.
2. Texture Format:Riot started changing some skins from DDS to TEX. This tool handles the conversion so your files work no matter what format the game wants.
The Universal Fix option covers all cases by generating every needed variation of your files. You can disable extras to keep the output smaller.
