Quote - ... a pz2 (pose) file can be applied to un-parented props, so long as you address them as "actor" ...

But you have to know the name of the prop in the scene, am I right? cf box_1 above. If there are two boxes in the scene, the second will be called box_2 and the pose won't work on it. (edited to add) That's a good thought about using readscript to load the prop. I had an application for that ages ago. If only I could remember what it was, now. :)
