I just upgraded to DS 4.5 Pro for 4.
I did it because I thought the idea of Instancing would be great for making scenery instead of having to load each bit and set it up manually. I can't find anything that tells me how to do it, no menu item or button to push that refers to it although it's on the 4.5 "what's new" page just before "Geometry Shells".
The new version doesn't save files like the old one and the formats have changed. okay, but when I open files with objects that have been hidden by clicking on the "eye" icon in the Scene Tab, they DONOT reappear. That is odd, but i only said that to warn other folks it might happen to them too.
Please someone tell me how to "Instance" props or other non-actor objects or I will be tempted to go back to DS4 !
