In UE 5.8 File diffs for InputMappingContext and InputAction no longer use the Details/Property diff window and open a text diff instead

As described - the diff tool for InputAction and InputMappingContext assets uses a text diff in 5.8, whereas in 5.7 it used to use a more user-friendly GUI.

This seems to be because UAssetDefinition_InputAction and UAssetDefinition_InputMappingContext were added at some point.

We are using 5.8.3 specifically, which is the first update we’ve done from 5.7.* -> 5.8.

Our local fix is to change the newly added AssetDefinitions to derive from UAssetDefinition_DataAsset instead of UAssetDefinitionDefault.

Thanks,

Dave

Steps to Reproduce

  • In editor (with a source controlled environment), create or make a change to an InputAction and an InputContextMapping asset.
  • Right click the asset in the content browser and choose ‘Revision Control’ -> ‘Diff Against Depot’

By default in UE 5.8 a text diff will open which is much more difficult to read.

In 5.7 a details/property diff would open (using the editor GUI) which was much easier to read.
