How to use this prompt

  1. 1

    Open the generator that matches the model and version above, and start a new image rather than editing an existing one.

  2. 2

    Set the output to 16:9 and apply the settings shown in the parameters panel — together those produced the 768 × 432 image on this page.

  3. 3

    Paste the prompt exactly as written. Changing the wording changes the image, so copy it before you edit.

  4. 4

    Paste the negative prompt into the separate negative field; this entry was tested with one.

  5. 5

    Generate, then change one thing at a time. The result will not be pixel-identical to the image on this page, because no seed is recorded for it.

Stable Diffusion exposes the sampler, step count, and CFG scale as separate settings, and this entry uses all three. If you are trying to reproduce this image, match the sampler name exactly and keep the step count and CFG as recorded — they are part of the recipe, not decoration.
