CG Rendering companies help Architects and Interior Designers present their projects and win presentations with excellent visual materials. Yet not all 3D companies provide the same level of services. Mistakes in choice lead to inferior quality of the three-dimensional rendering and complications at negotiations. Sometimes the colors aren’t correct, the scale is wrong or the overall rendering looks rough and therefore doesn’t do the design justice.
But all CG Rendering companies promise to deliver the quality that’ll amaze the clients and present the design in all its splendor. None of them says “Well, you know, we’re still struggling with V-Ray, but we are eager to try. What do you think?”.
How does one make the right choice in such conditions?
There are two ways to proceed:
- Trial and error: rely on intuition and accept that a certain quantity of failures is inevitable on the road to success.
- Examine the portfolio of a cg rendering company before starting communication. Analyze the quality of the renders the studio have done before and contact only the ones meeting all your standards.
The second option looks cheaper and more reliable. But how does one analyze a cg rendering properly?
Actually, this is something you can learn within 5 minutes. Just read these 5 easy criteria and use them every time you look at the portfolio of an Architectural Visualization Studio.
5 Criteria To Understand The Quality Of A CG Rendering
Now, let’s imagine you’ve opened the Portfolio page of a certain 3D company. The first look at the renders doesn’t make you scream in horror, so you proceed to more in-depth analysis.
#1. The Daylight Is Neutral
Sometimes you see that the cg rendering looks cold and lifeless. Everything is right, but objects have a bluish hue to them, and the overall impression is unpleasant.
That happens when the camera balance and V-Ray (rendering plugin for 3D Max) settings are off. The daylight should be neutral – like on the cg image above. The beams of light coming through the window are pure white, without a hint of blue. As a result, the restaurant interior looks bathed in sun, lively and inviting.
#2. The Nightlight At The CGI Rendering Should Be Cold
When the 3D Artist doesn’t follow this rule, the objects in cg render seem unnaturally yellow. For the same reason, the landscape by the window looks surreal and lacking life. Now, if the night light coming into the room is cold blue, the cg rendering looks beautiful, cohesive and the colors – flattering.
To create a comfortable night environment, 3D Artists must use Vray night HDRI environment instead of VraySky, and adjust Vray Light settings.Take a look at the Cafe 3D Render above. The cold light from outside interacts with the warm lighting of the room and fills it with air and crispness. This is obvious when looking at the curtains, flooring and wine glasses. The overall atmosphere is cozy, and the interior design looks harmonious.
The ability to set the light in 3D Max is definitely a mark of quality to take into consideration when judging an Architectural CG Rendering. For it can basically kill or create the image!
#3. The Light Emanates From A Certain Source
Sometimes there is a sort of “fantom” light in the architectural cg render that comes from nowhere. And you can see that the lighting is too sharp in the areas concerned. It looks unnatural, for materials thus reflect more light than they get from the source – the sun, chandelier or spotlights.
The origins of this mistake can be different. Most often, 3D Artist decides to liven the scene up and add additional lighting with Photoshop at the post-production stage, or increase the existing one. Anyway, it is important to remember that all light should come from a visible source and have a corresponding brightness.
Take a look at the interior design CG Image above from ArchiCGI rendering company. You find no light patches or materials looking burned out. The reflective surfaces shine evenly, and the quantity of light bouncing off is perfectly natural. One could mistake this render for a photography!
#4. The Composition Of The CG Rendering Has A Center
When there’s no centre in the composition, the architectural cg render looks blank and random. Much like a picture taken by accident – by a slip of the finger. It means that the 3D Artist didn’t apply the Rule Of Thirds.
The Rule Of Thirds is to divide the cg rendering into 9 even parts by 4 lines – 2 horizontal and 2 vertical. And the objects of focus should be placed at the intersection of these lines. As a result – the 3D interior render looks full of impact and harmony.
