All exec input pins use 'execute', all exec output pins use 'then'

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'

All exec input pins are 'execute', all exec output pins are 'then'

Universal UE5 Blueprint rule: exec input = 'execute', exec output = 'then'. Exceptions: Branch outputs are 'True' and 'False'. Sequence outputs are 'then 0', 'then 1', 'then 2', etc. ForLoop outputs are 'Loop Body' and 'Completed'.

Sequence — fire multiple exec outputs in order

Exec outputs are named 'then 0', 'then 1', 'then 2' etc. NOT 'Then_0' or 'Output_0'.

IsValid macro — check validity with exec branch outputs

K2Node_MacroInstance from StandardMacros. Has exec pins unlike the pure IsValid function.

FlipFlop — alternate between two exec outputs on each call

MultiGate — distribute execution across multiple outputs

DoN — execute N times then stop

Set

Writes a new value to a variable. The Set node has an exec pin so it runs in the execution flow.

Branch — conditional if/else flow control

DoOnce — execute the output only the first time it is called

Has 'Reset' exec input to allow it to fire again. Default bStartClosed=false means it fires first time.
