The Dawnhewn is Niahll's ship in my novel Solarum: The Continuance Crisis: a thirty-year-old Kestrel-pattern hopper working the lanes around Saturn. Nine metres of cabin that is basically a camper van, every centimetre doing two jobs, a fuel gland nobody can afford to replace, and a pilot who talks to it.
Inspiration, credit where it's due: the spark was the camper-van spaceship in Mel Brooks's Spaceballs (1987). A roughneck spacer riding around in what looks like a camper: my millennial heart loved that idea. The Dawnhewn is my own design in that spirit, not a copy of that ship.
What it does: gives you the same ship every time: a blunt, rounded cream hull with an ochre stripe, a dark window band at the front, two big engine bells at the back, grey radiator panels on arms, worn and patched paint.
How to use it
- Weight 0.9. Start from: jdhship, a small spaceship flying over the rings of Saturn, side view, sunlight
- Say a small spaceship and then the scene. It holds its look over planets, docked at stations, from behind with the engines lit, and at night with warm windows.
- Negative: 3d render, grey background, studio backdrop, text, letters.
What it can't do (yet)
- Landed on snow or ground it sometimes gets a blue sky and a blue stripe, or comes out tiny. It's a space ship first.
- "Next to a huge ship" sometimes turns the other ship into more of the Dawnhewn.
- The radiator panels show best at 0.9; at 0.7 you may get one or none.
- Interiors aren't in this one.
How it was made
I built a simple 3D model of the hull from the descriptions in my chapters and rendered depth guides from 60 camera angles (sun, half-light, night; panels open, and folded in a docking cradle). SDXL repainted each guide twice, once clean and once weathered, guided by the depth map. 127 pictures, captioned only with the view and the light, so the trigger carries the ship. No other people's art, nothing from Flux / Google / OpenAI.
Training: Juggernaut XL v9 base, kohya sd-scripts, LoRA dim 32 / alpha 16, UNet only, 1024 px buckets, AdamW8bit, cosine, LR 1e-4, 10 repeats, 6 epochs (1,908 steps), released epoch 6.
Made with Claude (Anthropic): Claude Opus 5.5 in Cowork wrote the 3D renderer and planned the method; Claude Code with Claude Sonnet 5.5 on my desktop ran the renders and training.
