A couple of initial questions:

1. Is the development build and development server projects built in Development mode (the names suggest that, but they could still be Shipping builds with extra stuff included)?
2. Did you try latest experimental version?

If they are built in development project target, then it makes sense this is happening, as the development target is not supported by UE4SS.

[Bluscream]

1. How would i get that information? And if so, there's no way to get even mods working?

• window title is ... (64-bit Development PCD3D_SM5)

3. Is there a newer one than the one on the releases? If so, where? I only saw a few forks with more functionality but theyre mostly outdated

EDIT: Just tried with fresh https://github.com/UE4SS-RE/RE-UE4SS/releases/download/experimental/UE4SS_v3.0.1-154-g1b5ff77.zip and exactly the same behavior

[Buckminsterfullerene02]

Ah yeah sadly I think it seems it is built in the development configuration. I'm not sure what exactly would be required in the backend to support that configuration, but as far as I know there are no plans to support it.

[Bluscream]

How would that differ from normal versions? Different memory offsets for entry points?

[Buckminsterfullerene02]

@UE4SS is probably better to answer that question

It's a few bytes added to the end of FUObjectItem. We will add support at some point.
