-In case you dont know how to install this mod here are the steps:
1. When you unzip the file you will get 3 files:
"Packagedefinition.txt"
"Chunk0patch6.rpkg"
"Chunk0patch8.rpkg"
2. Back up your packagedefinition.txt which you can find in hitman2/runtime (not retail or dx12retail)
3 next, copy both of the file you extracted (in step 1) to the runtime folder should you have installed any mods before this. You can rename chunk0patch6.rpkg or chunk0patch8.rpkg to another number that does not overlap. Foe example to chunk0patch6 or patch7.
4. Finally run the mods only in offline. Dx11 or dx 12 should not be a problem.
