Here are nine post-apocalyptic scenes for your zombies and Mad Max characters to roam around in; the file sizes are marked on the image names so you can set Daz's render size to match the size of the background image (Daz tends to compress images oddly if you don't tell it the size you are giving it.) If you like a scene, check the Readme and see if there is a matching product in the Marketplace-- so you can expand the scene with more 3d items in it for your character to interact with. I recommend all of ShaaraMuse's products for any scene that needs realistic rocks or grounds, and Flink provides some wonderful skies and plants. There is also Mapps and Richardphoto's "Horror Classics" that will fill out your scene with all the tools and debris your heart would desire :D
Thanks for checking this out!
