Determine a path by copying an eVar value to a prop

You can copy the value of an eVar to a prop to enable pathing.

When setting values, the variable on the left receives the value (even if it is empty) from the variable on the right.

Rule Set Value
Condition None (always execute)
Action Overwrite Value of Prop1 with eVar1

You can modify this rule to set the value of Prop1 only if it does not already contain a value, similar to the following:

Rule Set Value
Condition If Prop1 Is Not Set
Action Overwrite Value of Prop1 with eVar1

For example:
