Isometric ink style

Two LoRAs for Qwen-Image-Edit-2511 that turn a 3D isometric render of a city into an inked, hand-drawn-style illustration, and a painted day view into its night or golden-hour version. They paint Isometric Luxembourg and are used by Isometric Tehran, where anyone can help paint the map.

File	What it does
isometric-ink-v2.safetensors	Style: repaints an outlined part of a 3D render in the inked style, matching the painted image around it.
isometric-light-v1.safetensors	Light: turns painted day art into night, golden hour or a season, 1:1, keeping every line.

How they are used

The map is painted in overlapping windows over the whole canvas (MultiDiffusion), each window holding the parts already painted, so the result has no seams. The painting code and the step-by-step guide are in Isometric Tehran: docs/PAINTING.md.

Prompts are the training prompts, with the style token <isometric luxembourg ink>:

• Style: Fill in the outlined section with the missing pixels corresponding to the <isometric luxembourg ink> style, removing the border and exactly following the shape/style/structure of the surrounding image (if present).
• Light, e.g. night: Convert the outlined section to the <isometric luxembourg ink> style at night, warm and cozy, with no sun shadows, matching the surrounding image.

Typical settings: 25 steps, CFG 3 (style); 15 steps, CFG 3 (light). With the Lightning LoRA, 8 steps, CFG 1 (style).

Training

• Base: Qwen-Image-Edit-2511, trained with ostris/ai-toolkit, rank 16, learning rate 1e-4, batch 1.
• Style (ink-v2, step 2000): inked isometric drawings of Luxembourg City made with OpenAI's image API, paired with their 3D renders and turned into masked infill and full-view examples (the method of isometric-nyc and Pixel Singapore).
• Light (light-v1): painted day art paired with night, golden-hour and season versions of the same views.
