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)

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): A measure of how slowly light travels through a transparent medium than it does 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 for rendering coloured transparent materials.
- Roughness: Light scatters across a surface due to microscopic surface flaws. Roughness increases the matte appearance of a substance. 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’ll be able to 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, and 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, if you’re trying to replicate a product shot, a small amount of flaw might go a long way.
- 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 sell the realism. Roughness is used to make something appear as if it has been abraded 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.
