ZHM Mod SDK

A modding SDK and mod loader for HITMAN 3.

Description

This is a community-made modding SDK and mod loader for HITMAN 3. Its purpose is to allow users to easily download and use mods, and make the creation of more complex runtime mods easier for developers.

Right now it's at a very early stage, with only a few aspects of the engine exposed, but the plan is to further extend it to support basic entity, AI, and item manipulation.

Usage (mod loader & mods)

Download the latest version of the mod loader and the mods by going here, and downloading mod-loader-RelWithDebInfo.zip and mods-RelWithDebInfo.zip. These zip files contain the mod loader and a few mods respectively.
Extract the contents of the mod-loader-RelWithDebInfo.zip archive to <drive>:\Path\To\HITMAN3\Retail, where <drive>:\Path\To\HITMAN3 is the path to your Hitman 3 installation directory. This will be at C:\Program Files\EpicGames\HITMAN3 by default. Make sure that you extract the files in the Retail folder and not the root HITMAN3 folder.
Create a new folder called mods inside the Retail folder you extracted the mod loader to.
Extract the .dll files from the mods-RelWithDebInfo.zip archive to the mods folder you created in the previous step. You can find a description of what each mod does below.
Run the game like you normally would.
When the game opens, you'll see a dialog asking you which mods you'd like to use. Select them and press OK. You might need to restart your game for some of them to work.
...
Profit?

NOTE: You can at any time change the mods you're using by pressing the ~ key and selecting them, or by editing the mods.ini file inside your game's Retail folder.

Sample mods

There are a few sample mods included in this repository that can be used either as reference or for regular gameplay.

Mod name	Description
NoPause	Prevents the game from automatically pausing after losing focus (eg. when alt-tabbing or minimizing).
SkipIntro	Skips the intro sequence and starts the game directly at the main menu.
WakingUpNpcs	Makes pacified NPCs wake up after a random interval between 4 and 8 minutes.
CodeGen	Generates binding code from the embedded engine typeinfo which can be used by tools like ResourceParser.
CertPinBypass	Disables SSL certificate pinning, allowing the game to connect to any trusted server instead of only IOI's.
MaxPatchLevel	Dynamically sets the RPKG patchlevel to 1000, making the game discover patch chunks without having to modify the `packagedefinition.txt` file.
DebugMod	Adds a debug menu to test different SDK functionalities, like 3D rendering and entity information display.
FreeCam	Adds support for an in-game free camera that works with both KB+M and controllers. Can be toggled either from the SDK menu or by pressing `P`. For more details on available controls see here.
DiscordRichPresence	Sends rich presence updates to Discord with details such as level name, gamemode, etc. Requires additional setup!
