Visual Diff
Visual Diff on Flow Asset is available since version 1.3. It's gonna be enabled in launcher builds since UE 5.1 Preview 3.
It requires trivial changes in the engine code, so it's not available in launcher engine builds prior to 5.1 Preview 3. Epic engineer accepted this pull request in that engine version.
You can unlock this feature if you're compiling the UE 5.1 from the source.
- Merge the aforementioned pull request.
- Change the value of
ENABLE_FLOW_DIFFpreprocessor macro to 1.
If you'd like to have this feature in UE 5.0, there's much more work... You have to backport engine changes from 5.1.
- At least apply this one, then pull request mentioned above [Feature] Blueprints - Extract Details View of BP Diff tool and set the Fidd Override for UDataAsset types for this tool
- Visual Diff in 5.0 doesn't look as good as in 5.1. I guess this change might help, but I didn't test it: [BugFix] BP_Diff data flow changes
