I'm splitting these into two categories: 360* and 180* panoramic backgrounds. I realize that technically they are both "360" views, but for lack of better terms, this is what I'm going with. You will understand the difference when you look at them. Took me awhile to find some good ones, but I found the perfect "meadhall" background for the Skjaldborg. Some of you may recognize the location. I have 360* and 180* examples in the attachment below. The main difference is that 360* is seamless in VR while 180* panoramics have "deadspace" above and below. If you find any others, feel free to post them below. You can help your search by using keyword "HDRI"; this will get you much better HD pictures. Also I recommend only downloading images that are a minimum of 5000 x 2500 resolution. If it's a 180* panoramic, you can also mirror/duplicate the image to artificially increase the resolution (i have examples below). Anything less and they look kind of crummy as a background in TTS. TTS says it can only handle up to 4000 x 2000 resolution, but that is not accurate. From my own tests, anything under 10,000 x 5,000 resolution should load without crashing TTS.
I'm trying to come up with something for a Battletech-themed background that doesn't look like shit. Will post that later. In the absence of that, any 360* "alien landscape" or space image should do just fine.
