3D Visualization: V-ray or Corona Render?

Rendering Engines

Today we want to say a few words about rendering. In particular, which plug-in/engine to use to represent your project, in the best and easiest way.

The first and most well known is V-ray. This is available for most 3D modelling and animation software, such as Rhinoceros, 3D Studio Max, Cinema 4D, etc. It has been a “must have” for every computer and studio, working in the architecture or design sectors for several years.

The second plug-in, a fierce competitor of V-ray, is the new engine developed by the “Render Legion”. This is Corona Render. This software has been on the market in Beta Test for a couple of years. the complete and definitive version is available, for now, it is possible to use it only on 3D Studio Max and Cinema 4D.

Both plug-ins are excellent for realistic architectural visualization, but there are differences, albeit small, to take into account.

UX & Settings Vs Time

As for V-ray, it is now known that it is not very “User-friendly”. In order to get excellent results in terms of realism, there is a need to work a lot on the initial settings and on the rendering parameters. Furthermore, you need to set the right lights with the right tone and intensity, in other words sacrificing time.


On the other hand, Corona Render instead, has pre-set settings that are fairly good. Achieving a satisfactory result is simple, and is therefore useful for all those renders that do not have the task of capturing the customer’s attention. Obviously, for the perfect image, I want the perfect settings and lights. Without going around it, a work of art takes time, in this case we prefer V-ray.

Lighting Vs Time

To stay on the subject of lights and lighting, Corona also has a very unique feature called ‘Light-Mix’. The peculiarity of this instrument lies in the fact that it is possible to change the intensity, colour and tone of the lights in real time! To give you a concrete example, while you are rendering the exterior of a building in daytime view, and you decide you want to view the same scene in night mode, Corona gives you the chance to do it without having to render everything again. It will, in fact, be possible by simply adjusting the numerical slider. The use of ‘Light-Mix’ is not limited to the exterior of a building but is also very effective for internal images or for Still-life. This tool is a game changer, especially if you need to save time.


Another great thing about Corona, is that it has its own material library. This gives you the opportunity to practice applying materials without having to spend hours to create them by yourself. There are many categories of materials such as glass, wood, stone, etc. All of them available with a simple drag and drop. Anyway, it is good to point out that those materials are very basic, and having skills in developing them from scratch means to be able to fulfil the client’s requirements.

Viewport Vs Time

Still talking about timing, in both plug-ins there is the possibility of using the work viewport as a real-time rendering window.

In the past, V-ray was equipped with the “Vray RT” function. This was useful but cumbersome, and needed to load all 3D assets with each execution. Fortunately, now V-ray has made available the “IPR” function (interactive Production Render). This gives us the possibility to have a preview of the scene in a much more fluid way than in the past.


Corona Render instead presents itself with “interactive render” which has been designed and improved since the first versions, and is an integral part of the plug-in rendering engine. From the first tests this function was a little more smooth than the competition and no problems of any kind were found. With the same computer, in the other case, we experienced crashes or temporary blocks in rendering.


In conclusion, we believe that more experienced users will appreciate the qualities of V-ray more. At the same time, we advise new players to start with Corona, to benefit from the ease of use. If instead the interlocutor is an architectural firm, then we need to focus on hourly costs. There are four cases:

1) Your studio outsources all types of rendering. Having a rendering engine is good, if nothing else, it is potentially available. In this case, we suggest the cheapest and easiest to use: Corona Render (if applicable).

2) Your studio outsources artistic rendering and normal renders are performed by junior staff. In this case, we suggest the use of Corona Render (if applicable).

3) Your studio outsources artistic rendering and normal renders are performed by senior staff. Whatever your rendering engine, with a computer up to the required performance and with an artistic and compositional taste you will be able to achieve the desired results.

4) Your studio performs artistic renders and normal renders. Well, you don’t need any advice.

Those renders were made by our team within 45' using the same model and the same equipment



We at Airchitects possess the requisites and the skills necessary for architectural visualization and for an impact design. The render is the image that describes your and our vision of the project. In most cases it is the stylistic summary of the idea. It is that photo which, together with an excellent design, makes the customer fall in love and allows a jury to evaluate your proposal as the winning one.
