You cant use a 3d object directly in your GUI, but you can create a second camera that creates a render texture, or renders to a custom viewport.
If you set the camera ‘clear flags’ to no-clear, it will make the background transparent. Just put the depth of that camera higher than the default camera, otherwise it won’t show up.
Also a nice thing to do is create a different render layer for ‘3d gui’ and make your gui camera render only this layer.
