Tent in the desert. Can work with both indoors and outdoors views.
Tent is the main trigger, but others like inside a tent, outside a tent, outdoors, indoors, scenery, palm tree, cushions, desert and so on are useful. If background is a mass of tents, putting multiple tents in negative tends to help.
Do note that NoobAi works just fine with Illustrious, and in on-site generations resources for both can be used together when advance mode is selected in Additional Resources tab
