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.

Unlocking feature

You can already unlock this feature if you're compiling the UE 5.1 from the source.

• Merge this pull request, Epic engineer accepted this pull request in that engine version.
  • Adding KISMET_API allows creating visual Diff for custom node graph editors!
• Change the value of ENABLE_FLOW_DIFF preprocessor 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
