I tried opening up some of the dds files from textures.pak to view them with XnView but I can't seem to see anything. I would like to start work on replacing some of these low-res textures with improved ones. I only tried with Dolphin in the past and it was fairly easy. I'm not sure if you need to adhere to strict checksum/file sizes with games like these. Can I just replace the file with a new one using the existing filename and format? Anyway if anyone with prior experience can give some suggestions that'd be great thanks! The first issue is definitely sorting why everything is just coming up blank or black in XnView when trying to expose the existing textures. EDIT: So I've got some leads on the issue from various threads in the CryEngine forum and their official documentation. Something to do with CryEngine splitting the DDS files for less memory consumption? I still don't really know what the fix is though. The file included in the third link doesn't work anymore so I'm kind of at a wall.
