You will need to add specific packages to Terradome/Terradome2 to get exactly what you want.  They rely on props to build your scene which can become very intensive if you add too many item.  The work around for that, build your scene then render it to background.  Delete all the props in the environment and you have a perfectly effective background image to work with.  The Cyclorama sets predominately work with flat planes to build your scene, no complicated prop meshes involved.  But it depends how much background and foreground content is needed to build your scene.
