I made this tool to quickly get meshes and textures from the game files. I decided to polish it a bit and release it. It might be useful to someone. I tested it with weapons and characters so far, not sure how well it will handle the maps and other stuff.
It can decompress CRI and OFS3, so you can directly load the files in the "chr/mod" or "wep/mod" game folders. No need to decompress beforehand.
