Worldbuilding scene concept art: one base image extended into three atmospheres

Starting from a single scene base image, use image-to-image for a visual exploration of worldbuilding and atmosphere: under the same spatial structure, switch time of day, lighting, and weather to test what matters most at the concept stage — whether the intended atmosphere direction holds up. This piece was genuinely generated by the gpt-image-2.6-flare author route. The flare version emphasizes speed and suits high-frequency iteration during concept exploration; research also notes that this kind of scene concept art falls into the category of visual exploration where approximation is acceptable — if strict material, proportion, or text consistency is needed later, the approved result should be composited with the original image rather than relying on prompts alone. On the input side, only one required media field was used, image_urls (a single source image), along with non-media parameters: resolution set to 2K to keep details legible, aspect_ratio set to 16:9 to match the scene's horizontal composition, and quality and complexity left at their defaults to keep the shot structure stable. Output is png. Use cases: mood boards for game/film pre-production concepts, atmosphere references for scripts, and worldbuilding exploration that requires quickly branching multiple time-of-day and weather versions from a single base image.
