Bumping this because I feel like it’s much more relevant now that we have much more powerful Condo editing tools now.
Currently, the best way to create a fake skybox is via something like the Canvas Dome feature and a custom equirectangular canvas.
Glossing over the fact that this illusion falls apart as you get closer to the edge of the dome, a more important fact is that this solution is incompatible with a day/night cycle without advanced, expensive, custom Condo IO and multiple images for different times of day. Additionally, the inside of the dome is lit awkwardly beyond the ambient lighting of the current time of day. In order to get a convincing sky a glow of 1.0 is required.
There are custom built-in shaders available that solve the resolution and texture cache issue, but many aren’t mapped to the dome’s UVs properly, and this solution still isn’t compatible with the day/night lighting.
Being able to simply “duplicate” the natural condo sky seems like a solid way to fix this problem.
This feature would also be a great proof of concept towards this other feature request:
