HELP PLEASE!
I tested Clear Sky's unpacker and it worked with current mods for the S.T.A.L.K.E.R.: Shadow of Chornobyl – Enhanced Edition
However, I would really like to understand the proper way to create and pack mods for this version.
Should I study or use something like X-Ray SDK or another toolset?
My main goal is to learn how to:
Properly create mods for this Enhanced Edition
Understand the required format (like .pack)
And if necessary, how to pack or repack them in the correct structure
Any guidance or official resources would be appreciated. Thanks in advance, stalkers!

**ps: I have 3 mod for old vesion.
