Help Needed Modifying Game's Blueprints Using FModel and UAssetGUI

[Platapusopus]

I've been trying to follow this guide to general UE5 modding: https://github.com/Dmgvol/UE_Modding

I've managed to extract the game's mappings using UE4SS, and load the game's .pak and .utoc into FModel.

Where I'm stuck is editing exported .uasset blueprints that I've exported from FModel -- this is where modding guides seem to conflict with each other. The guide mentioned above has a page on UAssetGUI, where it goes through editing .uasset files exported from FModel with UAssetGUI -- this other guide for the game Ready or Not (also using UE5.3) explains the same here.

However, when I try to do it I get an error that explains:

Failed to open this file! Zen Loader assets cannot currently be loaded
directly into UAssetGUI. You can try extracting traditional cooked assets
from IOStore container files by using ZenTools by Archengius, or
otherwise try software like FModel or umodel to view the asset.

So I'm pretty stuck. I've exported the .uasset of the Blueprint I want to edit, but following these guides it doesn't work. 

Does anyone know how I can edit the exported .uasset file? And also why am I getting that error?

Same for me. I want to add new pieces of soundtrack, not replacing old ones, so I need to be able to modify .uasset files. I'm getting the same popup, and downloading ZenTools over GitHub wasn't of much help (it has a bunch of files with unknown extensions that I don't know what to do with).

 

Edit: I think we have to install Unreal Engine, then compile ZenTools in UE to be able to edit the .uasset files. I do hope someone can chime in.

Bumping, also need help

Yeah, I've been stuck at a similar place for days now. I tried Zentools too and it didn't seem to work or uassetGUI wouldn't read them or something, I don't specifically recall. 

The closest I've gotten was using retoc (there's a version with a GUI on Nexus somewhere) to extract the files. It extracts .uasset and .uexp or whatever the latter is and I can open the former in uassetGUI but I get an error saying some can't be read. Not sure what to make of it all. 

UnrealPAK and PAKMaster might be other means of extracting to look into but I'm not sure if they'll work better or not. 

I will say, I suggest joining the Discord as there are a fair few guides and a lot of people working on mods. https://discord.gg/E66ftwed Hopefully I'm allowed to post that. Seems to be much more active there. 

I hope someone is able to answer your question. I've posted about similar things and gotten no responses. Do please update if you figure it out! Good luck!
