Better skies and twilight for every building
The building is finished and the one day you could get to the site it was overcast, so the elevation you spent two years on sits under a flat gray sky in the deck. Competition boards want a dusk picture with lit windows. The early-stage study wants a mood image before the model is even massed. You want the picture to match the intent of the building without hiring a render team.
Sky Swap replaces the sky in a site photo with clear blue, a dramatic storm, or a pastel dawn while keeping the building, its reflections and its edges. Time-of-Day Changer makes a twilight version with warm interior light showing through the glazing. For the concept stage, Concept Art Generator in environment mode turns a written description of a site and program into a mood image for the pin-up. Downloads are full resolution.

Made in the Studio with the first tool on the route.

Good to know
- What if the building has a lot of glass that reflects the sky?
- Sky Swap handles the edges and updates the visible sky, but reflections in glazing are a judgment call. Check them after the run; if a facade still reads as gray under a sunset sky, Time-of-Day Changer relights the whole picture so the glass and the sky agree. Compare both results and keep the one that holds together.
- Do I need a rendered model to make a concept image?
- No. Concept Art Generator works from a description alone: "a timber library on a sloped urban site, evening, people on the steps." Choose the environment subject and it makes a mood image you can pin up. It's a study, not a drawing; use it to set the tone of the conversation, not the geometry.
- Which tool gives me a night version of a completed building?
- Time-of-Day Changer. Choose twilight, blue hour dusk or night, and the exterior is relit with the interior glowing through the glazing and the sky darkened to match. Sky Swap alone changes only the sky, so use it when the daylight on the building is fine and just the sky is wrong.
