In late 2023, SketchUp Labs introduced a tool that integrates generative AI directly into SketchUp Pro, Web, and iPad versions. It was initially a free Labs experiment.
Crucially, the most effective free plugins utilize "Image-to-Image" generation.

This maintains the architect's intent regarding scale and composition while elevating the presentation quality to a photorealistic or artistic standard.

If your plugin allows negative prompting, type words like "blurry, low quality, distorted, unrealistic materials" to filter out bad generations.
