A cliff forge for skyships # A cliff forge for skyships - [Model Chroma1-Flash](/models/chroma1-flash) - Portrait 2:3 - 1024 × 1536 · XL - 12 steps - Max quality - iPadMac ## Prompt and Settings Copy prompt A cliffside skyship forge, channels molten glass into ribbed hull sections, above a canyon filled with tethered work platforms and steam cranes. Vertical 2:3 view from a nearby ledge, looking slightly down at artisans as small silhouettes beside huge molds. Sunset strikes the glass stream while blue furnace light fills the rock chambers. Concept art, readable industrial layout, basalt, iron chains, ceramic crucibles, atmospheric depth, practical fantasy engineering. ### Negative Prompt Copy negative prompt text, watermark, logo, random machinery, melted anatomy, blurry silhouettes, flat lighting, low detail, cluttered composition Seed 671368693 Steps 12 Quality Max Size 1024 × 1536 Made With Private Diffusion on a Mac with Apple Silicon Share Make it on your own Mac with 24 GB or more. Nothing you type leaves the device. [![Pre-order on the App Store](/app-store/pre-order-badge/en/pre-order.svg)![Pre-order on the App Store](/app-store/pre-order-badge/en/pre-order-dark.svg)](https://apps.apple.com/app/apple-store/id6760593556?pt=96139298&ct=pd_other&mt=8) ## Why This Prompt Works This concept centers on a production site rather than a finished vehicle, which gives the design a useful sense of function. "Channels molten glass into ribbed hull sections" carries the main idea for Chroma1-Flash, while the ledge viewpoint explains scale and layout. The split between sunset and furnace glow helps separate canyon, machinery, and workers, and the material list supports a coherent production-design image. ## Recreate It in Private Diffusion 1. Paste the prompt into Studio and choose Chroma1-Flash. 2. Set Size to XL and Aspect Ratio to Portrait 2:3. 3. Type 671368693 into Seed. On a Mac, switch off Randomize first. 4. Paste the negative prompt into Negative prompt. 5. 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) - [Fantasy](/prompts/fantasy) -
