Knowledge of Materials Can Improve 3D Renders

Table of Contents

Every person has their unique perception, which shifts due to sights, experiences, and tales in the surroundings. When giving someone a tale or presenting your thoughts, remember that not everyone will be able to see the scene exactly as you imagined it. Some folks can quickly visualise a 3D image in their heads and comprehend your concept completely. Others may lack that skill and rely on you to provide an accurate visual picture. Clients are diverse and have a wide range of needs and ideas. They know what they want from their area but can’t visualise it in their heads regarding architectural design projects. That’s where your rendering abilities come in handy. Giving your clients a flawless perspective on a project is the goal of a 3D design. 3D modelling is one of the most important tools in architecture. Artists face a difficult problem creating the most realistic depiction to sell the idea with confidence. They influence the viewer’s vision by employing 3D design and rendering technologies. Let’s start with the fundamentals. 

Understanding the process of 3D rendering

You show your idea in the form of a graphic so that the client may view it the way you wish it to be. You represent a three-dimensional view of a specific space. You draw the form using software and exhibit it as a realistic image. Typically, a 3D artist will go through the following steps:

  •       Using software to create/model a scene
  •       Placing various materials on the model
  •       Adjusting lighting, shadows, and reflections, 
  •       Developing the model (rendering)

It’s now time to render in 3D. You will choose and organise materials for your object using 3D rendering tools. Rendering will make the material look as realistic as feasible by adding more and more properties to it. Today, 3D rendering is nearly unavoidable across various sectors and art forms, including commercials, movies, music, medicine, architecture, sports, video games, engineering, etc. Artists can accurately portray an exclusive interior design, a complete property plan or take guests on virtual excursions through other planets and dimensions, bringing all of the client’s ideas to reality. Architectural designs, engineering floor plans, product visualisation, interior design, and virtual tours are all examples of when rendering is used. 

Choosing the Materials

Engineers aren’t the only ones who study materials. You should be aware of a few things while choosing the rendering materials.

  •       Diffuse colour: It is often a material’s foundation colour.
  •       Specular Color: Mirror-like (non-diffused) reflections have a specular colour.
  •       Refraction Index (IoR) measures how slowly light travels through a transparent medium than in a vacuum. When the IoR of opaque material increases, the contrast between diffuse colour and specular highlights increases, making the material appear harder.
  •       Transmission: The hue of light that passes through a substance. Transparent materials such as glass and plastic are frequently coloured with this pigment. Transmission is the movement of light through a substance. Set your colour in the transmission property to render coloured transparent materials.
  •       Roughness: Light scatters across a surface due to microscopic surface flaws. Roughness increases a substance’s matte appearance. There is no such thing as a perfectly smooth material; roughness is a fundamental characteristic of all materials. Notice how the roughness of the textured material varies? This allows for determining the material’s finish.
  •       Colour: It is a realism-killer when it’s over-saturated and uniform. Use textures to produce colour variety and photo-reference to match colour saturation suitably. 
  •       Bump Textures: These are images used to provide illumination to give the appearance of physical relief to a surface. This might be subtle or obnoxious. Normal maps are even more effective than bump maps! They can provide more precise surface details. Bump maps have the disadvantage of not truly changing the contour of your model. This implies that the silhouettes will appear smooth even if the surface is uneven.
  •       Textures of Displacement: Use displacement maps whenever possible when adding textures. Displacement changes the form of the model’s surface by pushing and pulling it, resulting in a realistic texture. This is crucial for macro photographs or displaying the material’s edge or a product’s silhouette. While a bump texture can yield impressive results, a displacement will leave a physical imprint on the surface.
  •       The Texture scale: Check that your textures aren’t too big or too small. If feasible, use a real-world reference.
  •       Graphics or Labels: Adding labels or graphics to a product frequently makes it more credible. These elements are visible on our items; seeing them will help ground an image or object in reality.
  •       Feathering and Sharpness: Make sure the graphic has the right sharpening or blurring when employing labels and graphics on your product. Stickers and labels printed on paper are not vector-sharp. Ink bleeds are a problem for printers. If feasible, try to include this information in your labelling. Labels that are too crisp appear to be false.
  •       Imperfection: Nobody wants their product to appear to have been discovered in a dusty, abandoned barn. However, a few flaws might go a long way if you’re trying to replicate a product shot. 
  •       Dust: When applied with moderation, grime, smudges, and errant fibre all have a place. Use it sparingly because a little goes a long way.
  •       Scuffs, smudges, and residue: A rough texture that depicts skin oils, packing friction, or the production process will assist in selling the realism. Roughness makes something appear as if it has been irritated by packaging, scraped, or touched by a human.
  •       Discolouration: A swirl in metallic paint or a smidgeon of colour noise in plastic will help add some variety. 

Your ability to control various material characteristics will differ depending on whatever render engine you choose. The critical thing to remember is that the better you can mirror reality, the better off you will be. Using physically realistic materials can replicate reality with less reliance on your creative sensibility and more reliance on hard science and technology.


Why is it necessary for you to be aware of the materials?

The materials you employ to create a clear image are everything when it comes to rendering. It implies that learning all of the intricate intricacies of the appearance of different materials is your primary duty. Most 3D artists are neither interior designers nor architects. Despite this, they took the time to learn about the design features. It would be best if you also knew what materials are available, how to portray them, and what they are used for. Tables are made of one type of wood, whereas staircases are made of another. One of the things you’ll have to consider is which materials can be mixed and which cannot. Artists must be conversant with the materials’ specific properties. All factors to consider are how durable, flexible, and long-lasting they are and how they behave in the elements. Do they shrink or become injured at hot temperatures or like the cold? A 3D artist’s employment entails a variety of tasks.

1.      It feels better when you use the right materials!

After gaining a thorough knowledge of the content, the following step is to process it. If you wish to give the client a genuine picture of the project, you must comprehend the complexities of the process. You will know what the material is best utilised for once you understand its thickness, texture, and strength. However, this is insufficient. A 3D artist must be intimately familiar with the material. When processing, it’s critical to understand how each material reacts.  For example, if a particular sort of wood retains its shine or there’s a need to varnish it to produce a specific piece of furniture that seems exactly as we envisaged it or as the client desires. Consider creating a frame for a huge, ornate wall mirror. You choose the proper metal component for the space, build a model, and calculate the frame thickness in the rendering tool. When you take your 3D image to a genuine mirror designer, the first thing you expect is, “This metal frame thickness can’t withstand the mirror weight this large; it will distort and break.” In the processing step, material components like gloss, reflection, and flatness are critical to bringing the material to a proper form to fit the design and use of various things. We can’t stress how important it is to understand how the material is processed — if you overprocess it or don’t process it enough, it will appear unrealistic. As a result, you must determine how much of the material’s major components will be retained and how much will be reduced.

2.      In virtual reality, it’s important to maintain realism.

If you spend too much time in virtual reality, your projects and ideas will become unnatural, and everything else in your photographs will appear artificial. That is why you must pay close attention to the smallest details. As the virtual space becomes more detailed, it appears more convincing and living. We must not overlook that nature is imperfect to obtain a truly natural look. A client may be turned off by an image that is too perfect. Artists are sometimes commissioned to create such a perfect village, including houses, parks, and home interior. In this scenario, the customer perceives sterility and a bland home where he would not want to dwell. That’s why you should consider the atmosphere you would like to create and the little flaws that most authentically depict a given environment and give it personality. Nobody enjoys living in a sterile atmosphere. To feel at ease and cosy, we often add modest objects of value, photos, and memories that complement our living area. When pitching a project to a customer, it’s critical to show them a familiar scenario that they’ve previously imagined in their heads and then work to make it a reality. Artists frequently employ subtle techniques such as including elements that remind clients of things from their own experiences, which they can identify with. Even in an imaginary house, a fruit dish, a flower pot, or an umbrella sitting on a stand can substantially contribute to the natural look and feel.

3.      In 3D design, depth is crucial.

The depth is the most significant distinction between a 2D and a 3D image. A 3D image’s depth is best achieved by experimenting with light, shade, and reflection manipulation. That’s why 3D artists need to be able to draw, sketch and cast shadows. Natural light from the windows is generally utilised since specific settings in the area are presented with a precise moment of the day in mind. An artist wants to know which shadows fall on different things and in which directions depending on the daytime and the sun’s position. That is something you must remember at all times. You can’t, for example, depict a room having roof windows and shade one side of the objects or place shadows where they wouldn’t naturally fall. Light achieves depth in materials by leaving unique properties like material texture, fractures, roughness, and unevenness. As a result, the material has a realistic natural appearance. The spectator clearly understands the material, almost as if they could reach out and touch it.

4.      Creating a welcoming environment

It isn’t enough to create a perfect picture of the area by following all of the rendering processes to the letter. A building’s interior soul should be present. Even though the artist strives to portray everything realistically, the room does not always emanate a good vibe. The artist must accurately depict the atmosphere in a room. Remember what time of day or year you’re replicating as well. Is the light shining brightly enough to display the space in its grandeur, or is it raining, and everything has taken on a deeper hue? To connect with the space, the client prefers to witness particular scenes. If you’re creating a sunset ambience in your home, pay attention to the image’s spatial nuances, such as the play of light on items and reflections on houseplants.

5.      Clients should be fully immersed in the project.

The artist must inspire a good feeling in the clients and encourage them to engage with the space you’ve shown to show them the full scope of a design. They’ll be drawn to the image and wish to be a part of it. We’re here to aid if there are details that architects haven’t considered or haven’t figured out how to present to clients through our 3D design and rendering skills. The artist’s job requires involving the client in the project and the process. If you can communicate effectively, you will better understand your clients, their wishes, and their needs. Your ambitions and ideals frequently obstruct theirs. The artists are responsible for acting professionally and explaining why they cannot use specific methods or materials in a particular situation. Maybe the client likes a specific material and wants furniture manufactured but doesn’t know that combining it with the other components they’ve requested would be physically unfeasible. Since you are limited to firebricks for these kinds of applications, the client may not comprehend why the fireplace cannot feature a multicoloured brick they saw someplace. Clients will learn to temper their expectations when an artist understands the materials, which will help them better grasp the entire project.

Isn’t 3D rendering a lot of fun?

It can be as much or as little fun as you desire — unlimited options. You may play games and build people, characters, locations, animations, simulations, and structures using 3D rendering. You can design your virtual environment. Trends in this field are exploding, and there’s always something new to learn. 3D rendering is simply developing and intertwining with more and more businesses every day, just as art has so many directions.


Visualisation is the most effective tool for a landscape project, interior design, or architecture plan. A well-designed and professionally generated 3D graphic is the greatest approach to presenting your idea. The more realistic the setting appears, the more you grasp the materials employed in these businesses. As a result, more realistic representation leads to a better understanding between the client and the artist, so professional 3D rendering services should be considered.
