UE4SS

commit 0290bedac01f4acfdcbaa13c5a5a2fa14585a549

Date:  Thu Jul 2 17:02:48 2026

Built with Xmake

Patched to fix loadmap hook. SBZ sends a null FURL which UE4SS didn't support.

You will need to update the hook signature as well.

AllowModsMod by Narknon bundled with a corrected pattern.

Added unmatched signatures, broken VFtables and different class layout to match SBZ edits.

Use either this or nadz version. Both are UE4SS. For a normal user, you shouldn't see a difference unless you have a lua or cpp mod thatt need the full correct layout and the valid hooks.
