Previewing Scenes
After launching, Diffusion captures an image of the current viewport of your model in the Preview pane.
SketchUp Diffusion uses the viewport you see in the Preview pane as the original input for any generated output. After clicking Generate, one generated image will appear in the Preview pane and additional generated images appear as thumbnails at the bottom of the pane. Selecting a thumbnail will show that image in the main section of the Preview pane.
If you make changes to your model’s viewport, like changing the camera angle or editing your model, you can click Refresh () in the top right of the Preview pane to generate images with the updated viewport.
