I wrote a simple tool that extracts textures from Tekken 7.0 (2015) uasset files.
Drag a uasset file to tk7texturevanilla.exe and the tool will extract the texture.
Via command prompt
tk7texturevanilla <uasset-file> – Will extract a texture from the uasset file and output a DDS file where the exe is located.
tk7texturevanilla <uasset-file> -o <output-path> – Will extract a texture from the uasset file and output it to
tk7texturevanilla "D:\TekkenGame\Content\UI\flash\SW_UI_Makuai\Rep_RNK_PROMOTION_M_L.uasset" -o "D:\texturefolder"
