Hi,
OrthoSize : I made an action for this ( on the ecosystem), so you can replace that.
for the position, I would instead use the regular "set position" and get the camera pos, change the Y and then set the position, this way you remove any reflections and you are good to submit.
I got this as well, and the best way to handle this is to not use "set/get property in these cases". If you encounter a property you can't access using regular actions, let me know, and I'll provide a custom actions for this.
Bye,
Jean
