The main idea behind 3D or interior rendering is to virtually create spaces that almost give the same feel as an actual real-life room. With the help of various techniques and strategies, interior designers are paving their way to a much more advanced designing era.

Traditionally, designers rely on complex methods like floor plans, watercolors, or mood boards. Although they do a decent job, their level of functionality is not the same as interior rendering. 

In this article, we will dive into why 3D rendering is the future of interior design and how you can develop 3D models capable of improving your sales and profits.

What Makes 3D Rendering the Next Big Thing in Interior Design

Interior rendering might seem like a complicated task. But when you put in the effort, it can benefit you in several ways. Here are five crucial benefits of this technical approach.

How 3D rendering saves time?

Traditionally, Interior designers use hand-drawn sketches to show clients how their idea would look on a piece of paper. These sketches are not only complex but can take several days to complete.


With the introduction of 3D rendering, the trend has started to shift into something less complicated and more time-saving. It helps designers showcase their skills in a sophisticated and neat way that delivers fantastic results.

Imagine a scenario where you put in the effort to make a sketch, and the client asks you to angle it differently.

This means you’ll have to re-draw the whole thing from scratch, and even after that, post-production can only do so much. With 3D rendering, you can make the desired changes in a fraction of the time. 

With better and quicker options, interior rendering helps designers save considerable time in completing their projects.

Does it help clients in understanding Interior details clearly?

When interior designers leverage the power of 3D rendering, their clients get to experience things clearly and connect with them holistically. From the correct lighting and mood to texture and color, 3D rendering makes designs almost lifelike.

In contrast, hand-drawn sketches don’t provide a client with complete information in almost every aspect. Moreover, they don’t give an accurate idea of what the finished product would look like. 

Interior rendering allows clients to understand each and every detail in a way that leads them to crave your interior design. It essentially allows them to experience themselves in their dream spaces.

Is 3D rendering for interior design cost-effective?

Regarding cost savings, 3D interior rendering will surely help you save a lot of money. This applies both in the short term and the long time. You can cut costs with better initial planning and through final rendering and even post-production.

All boils down to better design presentations in which clients can appreciate and understand every detail, leading to quicker decisions and, in most cases, more trust between the designer and client.

Previously, designers used to rely heavily on hand-drawn sketches, which could be inaccurate, unreliable, and cost thousands of dollars. But overall, 3D rendering has taken the architectural industry by storm. With high-quality and affordable designs, professionals are switching to digital technology for this very reason. 

With the proper setups, interior projects can be completed quickly and with fewer mistakes, increasing cost-efficiency and sustainability. into

Better interior renderings = Increases Sales

Nowadays, it’s not enough to have a good concept only. You must stand out and captivate your audience to succeed in the market. 

Interior 3D rendering is the key to unlocking your customers’ emotions and imagination. By using crispy and flawless concepts, you can effortlessly grab their attention.

Unlike physical models, Interior rendering allows designers to promote their designs, increasing sales realistically.

Steps for successful 3D rendering of Interior Design

To create the perfect 3D models, you need to equip yourself with the proper techniques. 3D rendering is a creative science; the more you indulge yourself in it, the more you learn. Below are six essential steps to carry out the perfect rendering idea.

Choose the Right Software

Creating fantastic interior designs requires software that makes the job smooth and efficient. With every 3D project the first steps are to convert all ideas and 2D plans into 3D environment by modelling them. Luckily, various tools are available to help you execute any design you have in mind.

Sketchup

This tool is filled with some of the most notable interior design features. Sketchup is affordable, fun to use, and helps you create customized 3D models.

AutoCAD

This is one of the best programs in the industry. It is used for almost everything and offers complete flexibility. Moreover, it’s accurate and detailed, allowing users to edit every aspect of their projects.

Rhino 3-D

Offers everything while having a simplistic interface. With Rhino3-D, you can create anything from a simple 2-D line, curve, arc, or circle to the most complex and intricate organic free-form 3-D solids.

Whether you create the model in Sketchup, AutoCAD, Rhino 3D, or another 3D modeling tool, it must be imported into a render engine like V-Ray for 3DsMax or Mental Ray for Maya. 

As soon as you’re inside these programs, you can texture the surfaces with pictures of elements like fabrics and wallpaper to make your 3D model feel like an actual room.

Make Your Design Appealing even in 3D

The next step to creating a 3D rendering is to think of the perfect design. Once you have understood what type of space you are working with, interior rendering becomes much simpler. 

Nowadays, the concept of homes has evolved into something much bigger. Interior designing is not only limited to making aesthetically pleasing environments. It also includes adding the right amount of lighting, and textures, and most importantly, coming up with a brilliant idea. 

Moreover, 3D rendering is all about seeing things from multiple perspectives. That is why it’s best to surround yourself with people that can help light up your design’s blind spots.

Ensure Your Objects Are of the Right Size

Make sure the scale of your project is correct from the start. Changes in later stages are possible with additional scripts and plugins, but this may result in unwanted effects sometimes later in the rendering stages, leading to increased times to find and fix the issues.

With 3D rendering, you need to ensure that the objects you place match the overall size of your layout. Using objects of improper sizes leaves an awful impression on the client. Hence, when working on a project, it’s best to take things slowly to make sure that everything aesthetically falls in the right place.

Add High-quality Textures

Always use high-definition textures of at least 4K resolution for your final presentation. To reduce the responsiveness of the software, you can temporarily downscale the same textures and still use them during the drafts and concept exploring.

High-quality textures are another essential that adds an essence of realism to your design. Since 3D artists don’t use actual materials, textures are the next closest to creating chic and luxurious interior designs.

Using low-quality textures with incorrect scaling, unnatural colors and flat textures feels lazy and fake. Hence, high-quality textures can lead to positive client feedback.

Lastly, remember to modify your textures before you finish your design. Although gloss and reflectivity are essential, you should consider your materials’ roughness. This is especially important if your setting includes wood, metal, and stone.

Adjust Lighting

Most of today’s advanced 3D software used for rendering interior projects is capable of generating high-definition draft images with different lighting settings. A project can look very different and reveal even more spectacular details of the concept when illuminated differently, exactly as a lighting designer will test with their special software.

Another factor that brings textures to life and takes your space to a new level is proper lighting. Beautiful lighting and realistic textures go hand in hand. If you can’t showcase suitable lighting in your designs, it can severely impact your overall plan. 

You need to understand what choice of lighting fits your idea’s vibe. Using soft and inviting lighting in your design can create a soothing effect. On the other hand, bright lighting will give your design a more contemporary appearance.

Lighting is everything. It sets the perfect mood, directs the viewer’s gaze, and highlights textural elements across the image.

Final Postproduction for Better Presentation

Postproduction is where you can still alter the project’s appearance or specific parts. A project without proper postproduction can look very different and sometimes not reveal the full potential and effect of the presentation.

When marketing your final design, you want to convey your ideas in a way that ultimately gets you the job. As technology propels, newer and advanced presentation techniques are constantly popping up. Hence, you need the right post-production tips to deem yourself an expert.

Post-production is one of the most unappreciated parts of creating 3D rendering for your interior designs. It allows you to make changes, put in the sky you like, insert a background, adjust colors and correct the slight mistakes in your model. 

Photoshop and Lightroom are the two programs used for post-processing. However, you might need to use other software depending on the interior design project you’re working on. 

In short, post-production is the stage where everything in a rendering finally comes together to present the client with a powerful and sellable idea.

Key Takeaways

Now that you are fully convinced why you should be using 3D rendering, it’s time to sit down and create a strategy that could win you high-paying jobs. 

Remember, it can take time to learn and master interior rendering. Even with cost-effective and powerful tools, you may need a professional capable of executing your idea and generating a stunning design.
