How exactly can i make this work?

[PharahLong]

Hello, I tried your method with P4V, but it seems like something isn't working. So, I opened my command line and tried the following code:
[CODE]
python.exe "C:\Users\Long\Documents\uasset-diff-main\unreal_diff_uassets.py" C:\Users\Long\Documents\uasset-diff-main\foldera\BP_Patient_3.uasset C:\Users\Long\Documents\uasset-diff-main\folderb\BP_Patient_3.uasset
[/CODE].
However, nothing happened. There's no error in the Unreal logs either, just the console log below:
[CODE]
Cmd: diff C:\Users\Long\Documents\uasset-diff-main\foldera\BP_Patient_3.uasset C:\Users\Long\Documents\uasset-diff-main\folderb\BP_Patient_3.uasset
[/CODE]
(I tried it in Unreal instances 5.3 and 4.26)
If you don't mind, could you make a short video demonstrating how to make it work on your machine

Hey ! Its likely that the unreal instance I was using exposed the diff as a command but it is not in vanilla Unreal. I'm not at the same company anymore so I can't check that :D I'll expose it in a small plugin this weekend and add it to the repo with proper steps

[PharahLong]

Thanks for the clarification! It sounds like a handy feature. Looking forward to seeing your plugin in action!

[guillaume-haerinck]

The plugin is in the repo, it is simply a copy of the diff command but using diff.asset instead. I still don't get why the diff is not always exposed, but at least now there is a backup solution (I still need to properly update the doc)

Hello, did you figure it out?

Hello @guillaume-haerinck , I am using Unreal Engine 5.2.1, but I am unable to compile the plugin
