-
-The type `T` is determined by the referenced variable. The variable index **MUST** be a non-negative integer less than the total number of custom variables, otherwise the node is invalid and the graph **MUST** be rejected.

-This node has no internal state.

-When the `in` input flow is activated:
-
-1. Evaluate the `value` input value.
-2. If the _variable interpolation state dynamic array_ (defined below) contains an entry with the same variable reference, remove it from the array.
-3. Set the custom variable with the `variable` configuration value index to the `value` input value.
