Also getting this error with certain uAssets generated with ZenTools-UE4: AlienClasses.zip

Other uAssets generated from the same tool seem to be fine, it's just this one subset and maybe one or two others that generate the errors.

If necessary, I can provide C++ header files for examination.

Please create a separate issue with the engine version specified. Unless these assets come from the same game as the original issue, the two issues are unlikely to be related.

This asset just requires a manual map struct type override. In UAssetGUI, go to Edit --> Edit map struct type overrides... and add the following entry: OverridePreviewModel | null | SoftObjectPath Or, in UAssetAPI, modify the MapStructTypeOverride dictionary before calling UAsset.Read. You can also avoid having to do this by providing a set of mappings.

Do you know the different type of entries there is or where I can find the right usmap file ?

Which game are you referring to? I have a .usmap of Aliens: Dark Descent.

It is for a game called "The Cycle" made with UE 4.24.3, one of the uasset file say "Failed to parse 1 export" when I try to open it with UassetGUI, it's a file that contain a lot of data concerning objectives in the game. I'm gonna try to follow this (https://github.com/TheNaeem/UnrealMappingsDumper) to create a usmap file and import it as mapping, I hope it will work after that.

@antykoko Does UE 4.24 even need and have mappings?

I don't even know what mapping is... I'll be happy if you can teach me or if anyone have a solution for my problem.

People usually talk about 'mappings' if the game packaged with UE 5.+ and 'mappings' are required for editing assets (UE 5.+). But UE 4.+ games don't need 'mappings' to edit assets.

Why can't I open this file then ? it's a simple DataTable. On the link I sent, it also says "UnrealMappingsDumper is mostly targeted for UE5 games, as that's what most mappings dependent games use, but it should still work for the more recent versions of UE4."
