UE4SS is a Lua scripting system, C++ modding API and live debugger for UE4 games. This is an updated version of PD3 UE4SS / Allow Pak Mods.
This is the same UE4SS that comes with MoolahNet. If you already have MoolahNet installed, all you would need is the AllowModsMod folder in /Mods and to add AllowModsMod : 1 to the mods.txt

Steam/Epic Install
To install, extract the contents of the zip file into {GamePath}\PAYDAY3\PAYDAY3\Binaries\Win64

Xbox App for PC Install
To install, extract the contents of the zip file into {GamePath}\Payday 3\Content\PAYDAY3\Binaries\WinGDK

Note:
If you had a previous version of UE4SS installed, make sure to overwrite UE4SS.dll.
Any mods built for the old version of UE4SS will not work with this one. If you experience crashes on load, it is most likely caused by an outdated mod.
In the case that you find an outdated mod, contact the mod author to let them know to update the mod to rebuild the mod with this version of RE-UE4SS

This is what your Win64 or WinGDK folder should look like (Ignore the reshade or bodycam stuff)

ALLOWING PAK MODS WITHOUT -fileopenlog

Includes a mod to allow pak mods to work without passing the -fileopenlog parameter. This is now enabled by default. To disable it, open to Mods/mods.txt and set AllowModsMod : 0
This AllowModsMod is built to work with MoolahNet

Why use this mod over -fileopenlog?
Using -fileopenlog causes the engine to log the order in which it opens files. This means it takes longer to load into things. With slower HDDs this can be very noticeable.

Big thanks to Abkarino for helping along the way with updating AllowModsMod

Note:
If you are using linux, add WINEDLLOVERRIDES="xinput1_3=n,b" %command% to the launch options
