I'm not 100% sure what you're asking for, but I created my own crosshair mod with these 2 applications called DragonNest Model Browser and DN mods packer.
The dragonnest model browser is used to view .skn files and extract them. you can also extract any other files but you can only view the .skn files.
You can view .dds files by using GIMP and getting a plug-in for .dds files.
If you want to make your own .pak files download the zip i have below, you put the .dds, .skn, etc files into the folder called resource, then open the DN mods packer application. A pop up will come with random letters and stuff. There will be 2 buttons, click the one on the left. Then another pop up will come up. just press ok. A .pak file should load into the same location as the DN mods packer. That will be the file you move into the dragon nest folder for the mod.
when you download the mods packer, just extract it to your desktop or somewhere you can keep track of it.
BTW you might want to re-name the .pak file so that you can remember which mod it is.
