How To Make 3D Models For Games?

Video games are becoming increasingly popular nowadays as developers provide highly realistic graphics to gamers and offer the best gaming experience. You must have wondered how natural objects are put into video games, making them look identical to the real world.

Creating 3D representations of different characters and things is known as 3D modeling. 3D modeling is done by professionals using special software and drawing tablets so that the points in vertices can be manipulated easily, and an object can be formed by putting multiple vertices together.

It is a complex process, and you need to have excellent knowledge, experience, and skill to do 3D modeling properly. 3D Modeling can be done in mainly two ways; Manually or automatically. In the manual process, the mesh is deformed and given the shape of a particular object that you want to design.

On the other hand, in automatic 3D modeling, everything is done by the software, and all you need to do is give commands. There are several uses of 3D modeling, and one of them is video game development.

With the increasing popularity of video games, 3D modeling has become an excellent career option.

Different Techniques Used In 3D Game Modelling

- Image-Based Modelling

It is one of the most basic and uncomplicated 3D game modeling techniques used to convert images into 3D objects. For instance, if there is an image of the house, this technique is used to convert that into a 3D model, which can be used in video games.

For image-based modeling, a high-quality image and a drawing tablet are required so that each detail is easily visible.

The photo must be taken from different angles so that the 3D model can be designed from all angles and ensure that it looks realistic. It is one of the best techniques if you are short on a budget as it is quite affordable.

Usually, 3D modeling requires expensive software, high-tech drawing tablets, and incredible skills.

Still, if you are a beginner, you must go for image-based modeling as it won’t make you spend a considerable amount of money and help you learn a lot of things about 3D modeling.

- Digital Sculpting

With the increasing popularity of 3D game modeling, numerous advanced techniques have been introduced, and one of them is digital sculpting. It helps you learn how to make 3D models for games in an easy way.

If you want to create photorealistic assets without any manual efforts, there is no better option than digital sculpting. It is mainly used for creating a digital design that looks realistic using different digital tools.

There is numerous software in the market, such as Zbrush, Blender, to create 3D models of other objects. This technique allows designers and engineers to create 3D objects in mesh-based geometry, making them look more realistic and appealing.

You can choose drawing tablets especially designed for digital sculpting to create photorealistic designs.

- 3D Scanning

Another unique but popular 3D game modeling technique is 3D Scanning. It is a bit different from all other methods, and you need to have a unique 3D scanner to use this technique as it requires you to scan an object from different angles.

It uses the data gained from the scan to create a 3D digital model identical to the object. It is perfect for learning how to make 3d projects with minimum effort.

It is perfect for creating 3D models for superhero games as it will help portray the exact expressions and looks. It allows you to create a precise design with incredible detailing.

The only drawback with this technique is that you cannot use it on transparent or shiny objects as the scanner cannot scan them properly.

- Use Helping Tools

3D modeling is a highly complex task as it involves several aspects, and each one of them is equally important. If you focus on doing each task manually, it will consume a lot of time, and you will not complete your project at the right time.

Some tools, such as the Select N Edge feature that you can use to lower your workload and get better results with minimum effort. These tools can help you create intricate 3D designs and surfaces and objects such as clothes, baskets, wires, etc.

You can mold or demold different objects and create several designs with few clicks on the computers. If you are new to 3D modeling, you must use these tools to help you learn How to make 3D models and allow you to create better designs effortlessly.


- Use Deformers For Detailing

3D modeling is all about detailing as if the model doesn’t look realistic or identical to the real object; there is no use for it.

Gaining such a level of expertise is difficult in the beginning, so you must use deformers and selections as it will help you create intricate designs easily and that too, with perfect detailing.

All you need is a surface, and you can turn it into an attractive and complex 3D object by using deformers. It lowers your efforts and helps to create complex-looking designs with great ease.

It would be best if you kept in mind; you should use deformed only in Tileable surfaces as they are easy to work on and give much-needed detailing.

- Avoid Using Complex Tools

When you are new to 3D model making, you should focus on learning and use simple tools such as clay tubes, standard brushes, clay brushes, etc. The more you keep it simple, the better results you will get.

It would be best if you tried to use the fewest tools possible, as when you are a beginner, it will become challenging to manage advanced tools and learn to use each one of them properly.

3D modeling is already complicated enough, and there is no need to make it more complicated by using complex tools.

- Know The Terrain Tricks

If you are modeling an object for the first time, you must use the Edit Poly Mode better than Edit Mesh.

In Edit Mesh, you won’t be able to access crucial tools, and it will harm the final results when you start rendering the image. It will not give you the desired results as several issues related to face edges, quality, etc., will occur.

You can use tools like the Populate terrain script while using 3ds Max as it will fix all the issues related to the faces, edges, and quality.

- Think Smart

It would be best to focus on several areas while designing a game scene, but only a specific part of that area is under the camera focus.

So, instead of working for long hours developing all the areas, you must focus on modeling objects and areas seen in the camera angles. You can use the saved time to provide more details in concentrated areas and items.

Try to use tools like drawing tablets and software specially designed for 3D modeling to create complex models with maximum ease.

1. How are 3D models used in games?
- 3D models in games are used for creating characters, objects, and environments to give them a three-dimensional appearance, enhancing the game's visual realism and interactivity.

2. Can AI make 3D models for games?
- Yes, AI can generate 3D models for games through techniques like generative adversarial networks (GANs) and neural networks trained on 3D data.

3. What language is used for 3D games?
- Various programming languages are used for 3D games, with popular choices including C++, C#, and Python, often in combination with game engines like Unity (C#) and Unreal Engine (C++).


3D modeling is quite a lengthy and tiring process, and if you think smart, you get to enhance the results while saving a considerable amount of time and effort.

It is one of the best tips for beginners, as most novice designers waste a lot of effort working on things that are not even important. So, you must think smart and know that way to minimize your efforts and enhance results.
