Universal UE5 Blueprint rule: - All exec INPUT pins are named 'execute' - All exec OUTPUT pins are named 'then' EXCEPTIONS: - Branch: outputs 'True' and 'False' - Sequence: outputs 'then 0', 'then 1', 'then 2' (with space) - ForLoop: outputs 'Loop Body' and 'Completed' - ForEachLoop: outputs 'Loop Body' and 'Completed' - Delay: output is 'Completed' - DoOnce: output is 'Completed', reset input is 'Reset' - FlipFlop: outputs 'A' and 'B' - Gate: output 'Exit', inputs 'Open'/'Close'/'Toggle' - IsValid: outputs 'Is Valid' and 'Is Not Valid' - CastTo: outputs 'Cast Succeeded' and 'Cast Failed'
