2K17 to 2K18

[LexRed]

Hi again, just wondering if it is possible to use mods from 2K17 to 2K18. i have tried with some ch.pac but the game doesn't read them. At least they keep appearing with their original attire

 You'll have to add an entry pointing to the .pac files to the Chunk0.def file and also make sure that the IDs, Attire numbers and attire types are set correctly in the file name as well as inside. The best way to do this is to use Custom Character Tools' Regenerate Chunk0.def function.
Also, I suggest installing all your mods to the \WWE 2k18\mods\<ModName>\ folder (or just use CCT to install them, which is the safest bet anyway).

Be aware, however, that not all older mods will work in WWE 2k18 off the bat without proper porting. Some will, some won't, it's a hit and miss.
