On port, once exposed in Xpresso is requiring a trigger and is only processing the data while trigger is true
@Scott Williams
Just out of curiosity, why aren't you using nodes? It is far more advanced and offers vastly better functionality and versatility than Xpresso.
Ok, I figured out the 'why' ! If there is an unconnected ON port in the Xpresso node for that object it breaks the 'enabled' port for some reason (I imagine that might be a bug so will report it for you). But at least that is a mystery solved ! 🙂
