Hey, I’m not completely sure what you need help with — could you explain a bit more about what you’re trying to do? If you're looking for a way to extract textures from CHKN files, you might find this tool useful: https://www.imvumafias.org/community/viewtopic.php?t=11735. It’s a CHKN texture extractor that can pull textures from product files. Check out the post, and let me know if that’s what you were looking for - or if you need help with something else entirely!
