Polar seed vault crawler # Polar seed vault crawler - [Model Kroma Turbo](/models/kroma-turbo) - Landscape 3:2 - 1536 × 1024 · XL - 10 steps - Max quality - iPadMac ## Prompt and Settings Copy prompt A polar seed vault crawler serves as the subject, crossing blue ice on six heated treads toward a buried greenhouse dome. Adult technicians in padded suits guide insulated seed canisters along a ramp while aurora bands ripple above radar masts. Snow ridges, solar mirrors, and modular habitat pods span the wide view. The camera uses a clean side profile with slight overhead angle. Cold twilight meets warm cabin glow. Kroma Turbo delivers practical concept art detail and readable vehicle design. ### Negative Prompt Copy negative prompt readable text, logos, watermark, blurry vehicle, broken treads, duplicate workers, oversaturated aurora, low detail Seed 203916467 Steps 10 Quality Max Size 1536 × 1024 Made With Private Diffusion on a Mac with Apple Silicon Share Make it on your own Mac with 24 GB or more.

The “clean side profile with slight overhead angle” phrase carries the composition, exposing the six heated treads, ramp, and greenhouse destination. Cold twilight against warm cabin glow separates exterior and interior spaces, while seed canisters, radar masts, mirrors, and habitat pods create believable production-design detail across the wide aspect ratio. ## Recreate It in Private Diffusion 1. Paste the prompt into Studio and choose Kroma Turbo. 2. Set Size to XL and Aspect Ratio to Landscape 3:2. 3. Type 203916467 into Seed. On a Mac, switch off Randomize first. 4. Set Steps to 10. 5. Paste the negative prompt into Negative prompt. 6. Switch on Max quality (slower). Those are the settings that made this picture, and they run on your own Mac with 24 GB or more, with nothing uploaded. ## Filed Under - [Concept Art](/prompts/concept-art) - [Vehicles](/prompts/vehicles) -
