3D architectural renderings are becoming increasingly popular with architects as a way to show clients what a finished project will look like. This is more realistic than using a scale model or a drawing by an artist.
However, for architectural rendering to be victorious, it must be as photorealistic as practicable. Here are a few suggestions that are given via https://www.bmoutsourcing.com/services/3d-rendering-and-visualization/ considered a well-known firm for offering rendering services on how to get a higher level of realism in your visuals.

Chamfer your edges.
Even with man-made objects, there weren't any very sharp edges. By tilting your edges with the tilt tool in the preview software, you not only make your preview look more realistic, but also deliver out more details by engaging the edges to capture the accents of your light source.
Do not use colors that are 100% black or white.
To show that an object has volume, you need a highlighted and shaded area with a contrasting tone in the center area. If you have a virtual element that is completely black, your design will seem flat as the difference between the shaded area and the midtones are not visible. The same is true for the all-white model, except in this case the difference between the center and light areas is not visible.
Use blurry backgrounds or depth of field effects.
In your 3D architectural visuals as there is a certain amount of blurring associated with real-world photos to show movement. You can apply a depth effect during actual rendering or add it to post-production by utilizing the lens blur and depth z functions.
