What should I do if the furniture copied by Sue is missing when rendering?

Stick it somewhere else, and you can find it if you shrink it.

Reopen a file, then import all the original scenes and render them in the camera. It is normal. When opening 3D software and rendering a problematic scene, the lack of model in the rendered map may be a view error. Before rendering, we should render in the camera view, which is usually displayed in the upper left corner of the view.

The rendered view should be correct, and sometimes we know it is camera view rendering. However, when you accidentally click something wrong during rendering, the currently selected view box will be displayed. For example, this default yellow box indicates that the view is the current view. Renderers usually render the current view.
