If you need professional 3D visualization, especially for
interiors, then I recommend turning to professionals. For example, there is a
great company called Render Vision. You can see examples of their work on their
website, and they do just amazing 3D interior visualization. Here is the link,
see for yourself https://render-vision.com/type/interior-visualization-services/ . Of course, it costs money, but the
result will definitely not disappoint you.
