The window has three panels. The left panel picks what to capture, the center panel shows the preview, and the right panel holds the output options.

SceneLighting, environment, floor and post processing of the preview scene. See Preview Scene.
SettingsAll plugin settings. See Settings.

Preview​

  • The header shows the thumbnail resolution and the Capture Thumbnail button.
  • The preview has the same aspect ratio as the thumbnail, so what you see is what is captured.
  • The frame corners and the crosshair help you center the asset. They are not part of the capture.
  • The arrows on the edges rotate the camera, and the − / + buttons in the lower left change the camera speed.

Overlay badges​
