Manage thumbnails

Thumbnails help identify the asset, a States entry, or an individual option. The add-on reads embedded glTF image payloads and ThumbnailBase64 data and can write updated thumbnails back to the extension.

Thumbnail targets

You can edit:

• the asset thumbnail in Overview;
• the State thumbnail in State Settings;
• the option thumbnail in Edit Option Settings.

Capture from the 3D View

1. Frame the subject in the 3D View.
2. Open the thumbnail controls for the intended target.
3. Click Capture.
4. Confirm the preview image.

The add-on captures the current 3D View and normalizes it to a 256 × 256 PNG payload.

Load an image

1. Click Load in the thumbnail controls.
2. Select a PNG, JPEG, or GIF file.
3. Confirm the normalized preview.

The selected image is stored as PNG data regardless of its source format.

Clear a thumbnail

Click Clear in the thumbnail controls to remove that thumbnail field. Clearing an option thumbnail does not delete the option.

Capture, load, and clear actions mark the extension as dirty. Save the blend to retain the project, or use Save Changes to Source or Export Model + States to persist the change.
