In my novel Solarum: The Continuance Crisis, the people of Isla Buena live in sea hulls: spinning drums ten kilometres across, moored near Saturn, where a shallow tropical sea runs all the way round the inside. Stand on the shore and the sea doesn't stop at a horizon. It climbs up in front of you, islands and reefs and all, and hangs over your head.

What it does: puts you at eye level in a stilt village, on a white beach, on a dock or in a boat, with the sea rising behind and hanging overhead.

How to use it

- Weight 1.1 (1.0 to 1.2).

- Always add: the sea curves up into the sky and hangs overhead, islands and reefs above

- Start from: jsrise, a stilt village over shallow turquoise water, the sea curves up into the sky and hangs overhead, islands and reefs above

- Best foregrounds: stilt villages, beaches, boats and boat decks, lighthouses, harbours. Works at dusk too.

- Negative: top-down, map, whirlpool, tunnel, cartoon, 3d render, text, letters

What it can't do (yet)

- The trigger alone gives a sunrise ("rise" is a real word; my mistake). Always give it a subject.

- Markets and towns drift toward thatched stilt huts.

- At 0.9 it keeps your subject but often loses the climb; at 1.1 it climbs but pulls toward its own look.

- The sea overhead is painterly and softer than the foreground.

How it was made

A 3D sea hull built in Python (no 3D software), rendered from 30 eye-level camera spots. SDXL painted over each view, repainted only the near band at eye level, then blended the whole picture. 38 pictures, captioned only with what's in the foreground, so the trigger carries the climbing sea. Full story: Building Solarum, part 8 (coming soon). 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, 15 repeats, 6 epochs (858 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.
