How to generate thumbnails for scenes in CE.SDK

CE.SDK supports thumbnail generation in two contexts: running headlessly in the background without any UI, and generating a thumbnail at the moment a user saves their scene inside the full editor.

Option 1: Headless thumbnail generation for static scenes

You can initialize the CE.SDK engine without a UI, load a scene, and export a page as a JPEG or PNG at a reduced size. This is the right approach for background processing pipelines where no editor is visible to the user. The Batch Processing guide covers the full setup, including memory management and error handling.

Option 2: Headless thumbnail generation for video scenes

For video scenes, CE.SDK also supports seeking to a specific timestamp and exporting that frame as a thumbnail. This is covered in the same Batch Processing guide under the video thumbnail section.

Option 3: On-save thumbnail within the full editor

If the full CE.SDK editor is already loaded, you can generate a thumbnail at the moment a user saves their scene without any separate engine initialization. The engine is already running, so you simply export the current page at the point of save. See the Export overview for all available export options and formats.
