FO4-Wrench is a configurable mod for Fallout 4, with fixes and behavior modifications mainly for odd aspect ratios.

• Adds options for modifying scaling behavior of each individual UI clip. This fixes scaling for most of the default UI elements in non-16:9 aspect ratios, and allows UI modders to create a single version of their mods that will work with all aspect ratios.
• Fixes the placement and scaling of UI backdrops in non-standard aspect ratios, so they no longer appear misplaced.

It is implemented as a wrapper around XInput since the game voluntarily loads the XInput dll, and the XInput API is tiny enough that wrapping it is just about effortless. Simply drop the dll in the game folder to get started. See the configuration section for fine-tuning.

Note that since this mod only changes native behavior and no assets, it should be compatible with any mods that don't modify the game in the same way.

MSVC is the only supported compiler, and Visual Studio 2015 is likely required as I've made no effort to support older versions. You will need a version of the Windows SDK that comes with DX11 headers (it should have been included in the Visual Studio install). Compiling should just be a matter of opening the solution and building. All the remaining dependencies are embedded in the project.

FO4-Wrench is configured through a TOML file named Wrench.toml inside your Documents\My Games\Fallout4 folder. If that folder does not exist, either create it or simply launch the game as that will create it for you. All configuration options are optional.

• XInput.Path

  The path to the real XInput1_3.dll.

• Features.feature

  Boolean enabling or disabling individual mod features.

  • BackdropFix: Enables or disables the backdrop aspect ratio fix.
  • UiScale: Enables or disables UI clip scaling.

• UiScale.filename:

  The scale mode to use for the UI clip with the given filename. The path should use forward slashes, not backslashes. Requires UI clip scaling to be enabled. You may inspect the Wrench.log file next to the configuration file for the possible file names, and their current scale mode. Please note that file names are case sensitive.

  Possible options are:

  • "NoScale": No scaling, the UI clip's native size will be used.
  • "ShowAll": Resize the UI clip to fill the viewport, while maintaining aspect ratio. No clipping is applied, so UI clips may use the full viewport size.
  • "ExactFit": Resize the UI clip, disregarding the aspect ratio. If the clip's aspect ratio is not the same as that of the viewport, it will be stretched to cover the viewport.

• "NoBorder": Resize the UI clip to fill the viewport, while maintaining aspect ratio. Contents outside the normal aspect ratio may be clipped.

Note that the below values are used by default even when not specified. You only need to specify them in the config file if you want to override them.

Please note that the default UiScale settings have only been tested in a 21:9 aspect ratio. They should still work fine with other aspect ratios, but should you encounter issues, please create an issue.
