I have a whole bunch of background images, and I am not sure where they should be copied to in the DAZ 4.5 file arrangement as there is no installer for Backgrounds?
Any help would be appreciated,
Backgrounds do not need to be installed and I know of no way to install them even if one can.
I'd put those backgrounds in (if you have Windows 7) Libraries>Pictures>My Pictures.
Then while Daz Studio is open, go to Edit>Backdrop. Click on it and a small box appears. Click on Browse and find your backrgound you want and load it up.
You can use those backgrouds with any scene.
I made a folder in the textures folder named 'Backdrops' and put them in there, in folders by vendor (some of them I even remembered to put the ReadMe in with them). Since I have all my content on its own drive, I find this is the easiest thing to do.
Great information, thank you so much! :-)
