A difference in preview and export

Cropped screenshots show us nothing about your composition or your workflow. The first thing you child check is that you are using the Active Camera view. All other camera views will not render. If it is not a problem caused by rendering using a custom view or maybe the front view, take a screenshot of the entire UI. Make sure that the main comp is selected in the Project panel so we can see the Composition settings, select the VC orb layer and press the 'u' key twice to show us all modified properties on the layer. If you have a camera, show us the modified camera settings. When you have the screenshot, please drag it to the reply field or use the toolbar to embed it so we can see it without downloading the images. The Drag & drop here button should only be used to share project files.
