To try the new version of SketchUp Diffusion access the Centercode Project here.
The Negative prompt field performs the opposite job of the prompt field at the top of the dialog, and allows you to describe what you DON’T want Diffusion to include when it generates a new image.
To access the Negative prompt field:
- Expand the Settings accordion menu,
- Find the Negative Prompt text box below the sliders and enter the prompt
- Click any of the Diffusion models (Generate, Preserve Color, Relight)
