Variable node pin naming rules in UE5 Blueprints: - GetVariable: PURE node — NO exec pins. Single output pin named exactly after the variable (e.g. 'Health'). - SetVariable: exec in='execute', exec out='then'. Input pin named exactly after the variable (e.g. 'Health'). Output pin named exactly after the variable (returns new value). - Variable names ARE case-sensitive in connections. 'MyHealth' != 'myhealth'. - When connecting to SetVariable, the input pin name MUST match variable_name exactly.
