Scene Concept Art Upscaling: Clarifying Worldbuilding Atmosphere

A backend processing example for a scene concept art workflow. First, image generation is used to produce a low-resolution worldbuilding atmosphere sketch (ruined coastline, megastructures, skylight in mist), which is then passed to Recraft Crisp Upscale for image-to-image upscaling to boost resolution and sharpness while preserving details such as mist gradients, building edges, and water reflections, with targeted handling of small-scale textures and face regions. Since Crisp Upscale itself does not generate imagery and only accepts a single public image URL (JPEG/PNG/WEBP, single file no larger than 10MB), this work splits "generating the reference image" and "upscaling" into two steps: assets is responsible for producing the source image to be upscaled, and its bound path is the schema's sole required media field, image_url. This structure is suitable for plugging an upscaler into an existing image pipeline—for example, concept design drafts, small marketing assets, and restoration of old material—uniformly raising usable resolution before printing or downstream use. It should be emphasized that the results of denoising and detail reconstruction are not guaranteed; if the upscaled result does not meet expectations, it still needs to go back to the generation or manual stage for further processing. Applicable scenarios: batch clarification of concept art for worldbuilding and atmosphere exploration, post-upscaling of design model outputs, and readability restoration of low-resolution reference images.
