Visual Diff

Visual Diff on Flow Asset is available since version 1.3.

It requires trivial changes in the engine code, so it's not available in launcher engine builds yet.

• Adding KISMET_API allows creating visual Diff for custom node graph editors!

Unlocking feature

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_DIFF preprocessor macro to 1.

It's probably possible to enable this for 5.0, but you'd need also backport this engine change
