Hi Rudy, thanks for sharing this - there’s really soooo much valueable information, great resource.

Just a comment in case someone runs into stupid problems like me, just silently failing the condition:

This one is BAD:

UPROPERTY(EditAnywhere, Category = "Test", meta = (EditCondition = "Variable > 0.0f"))

The correct one works

UPROPERTY(EditAnywhere, Category = "Test", meta = (EditCondition = "Variable > 0.0"))
