3D Modeling for Games: Techniques, Software & More

by | Apr 29, 2024

Do you want to learn how to use 3D modeling for games? Then you’ve come to the right place.

In this article, we’re going to break down the techniques used in 3D modeling for games and give you a list of the best software to use. Let’s dive in! 

You’ll learn…

 

How is 3D modeling used in games

Over 250,000 people work in game development in the US. At the same time, the industry generates $176 billion yearly. At the same time, the VFX and animation job market grows by 8% every year, which is faster than average. 

In other words, there’s a lot of opportunity in this field – with 3D modeling playing a key role in the game development process. It’s used to create different kinds of visuals, such as:

  • Characters. 3D modeling for games is what gives video game characters their appearance. 3D modeling artists form every detail meticulously to give the character a unique look. 
  • Objects. Artists craft a wide range of objects like vehicles and weapons for use in video games.  
  • Environments. To create a truly immersive experience for players, intricate environments are made as a backdrop to the story. 

As a 3D game modeler, you are in charge of creating a character and backdrop that are interesting, fun, and visually striking. It’s a crucial step in the game development process.

The most important 3D modeling techniques

Now that we’ve talked about how 3D modeling is used in games, let’s explore the techniques you use as a 3D modeling artist to make models.

  • Polygonal modeling is used to create 3D objects using polygons, which act as building blocks that form the structure of the 3D model.
  • Digital sculpting is a process of shaping virtual objects to create the desired look for a character, creature, or other element.
  • NURBS are used to define curves and surfaces mathematically using weights, knots, and control points to build 3D objects.
  • Procedural modeling uses algorithms and parameters to form 3D models instead of the typical process of changing individual elements.

Okay, now that you know how 3D modeling is used in game development, let’s take a look at how to create 3D models for games   

How do you make 3D models for games in 6 steps?

3D modeling is a field that’s both artistic and technical. Let’s take a look at exactly how to use both skills to create 3D models for games. 

1. Collect references and draw 2D sketches

The first step is to identify the type of model you want to create. Is it an object, a character, or an environment? 

Next, gather references to help you visualize the model. Concept art websites like CharacterDesignReferences.com are great places to look. 

Once you have reference images, it’s time to draw your own 2D sketch. You can use pencil and paper, or a digital drawing tool, whatever works best for you. Don’t be afraid to sketch several versions to refine your idea. 

2. Create high-poly models

Once you have a 2D sketch that you’re happy with, it’s time to create high-poly models. Here’s a breakdown of how to do it:

  • Choose a modeling software suitable for creating high-poly models. There are many options, including Maya, ZBrush, Blender, and Modo. If you’re on a tight budget you can use Blender, which is free. 
  • Choose a technique. Depending on the complexity of your model, you can use sculpting, polygonal modeling, or a combination of the two.
  • Create the base mesh. You’ll want to start with a simple shape and add refinements using the tools in your chosen software.
  • Use sculpting tools to add details to your model.

3. Retopologize for real-time rendering

Retopology (AKA retopo) involves replacing the polygonal structure of a 3D model with a more efficient topology. 

High-poly models make for inefficient rendering, so retopo is used to reduce the polygon count and improve the rendering efficiency. Here are the steps to do it:

  • Prepare the high-poly mesh by fixing any errors. 
  • Create a low-poly base mesh using the high-poly model as a guide.  
  • Use retopology tools to add the details of the high-poly model to the new, low-poly mesh. Most major 3d modeling programs (for example, Maya, Blender, and ZBrush), come with retopology tools.

Even though retopology is a time-consuming process, it’s an important step in preparing the 3D model for rendering. If you’d like to learn about efficient rendering, check out this article.

4. Flatten 3D models into 2D images (UV Mapping)

Once the retopology is done, the next step is to get a UV map of the 3D model. Take these steps: 

  • Add seams along hidden areas of the 3D model. This article gives more info on seams and how to use them.
  • Choose an unwrapping method that fits the shape of your model. There are many different methods including Peel, Unfold, and Cylindrical. This article talks more about UV mapping and unwrapping.
  • Use the tools included in your software to spread out the unwrapped pieces on the UV map. Make sure to avoid overlapping pieces as this can cause problems during rendering.
  • Once you’re happy with the layout, export the UV map.

Maya has many great features for UV unwrapping. If you want to learn how to use Maya, read this article on how to choose a Maya animation course.

5. Add texture to your models

Once your UV unwrapping is done, it’s time to add texture to your model. The steps to take are:

  • Get textures to use. You can find textures online on sites like Textures.com, or you can make your own. Things to consider when choosing a texture are color, resolution, and detail.
  • Once you’ve chosen a texture it’s time to apply it to your model. 3D modeling programs like Maya and Blender include a material editor that you can use to apply the texture to your model.
  • And when you’ve added the texture you want, you’ll render your model. Learn more about rendering with this class. After the rendering is complete you can evaluate the outcome and decide whether you’d like to make any more changes. 

6. Rig your characters

We’ve now come to the last step. Excited? Let’s go!

Rigging your characters is a crucial step. Essentially, rigging brings your characters to life by giving them the structure needed for animation. Here’s how to do it:

  • Most 3d modeling software comes with rigging tools. Use these tools to create a bone structure that aligns with the movements you want your character to be capable of. If your character is human, you’d make bones for the head, back, limbs, and even the fingers and toes.
  • Connect the bones to the mesh (which acts like skin). This brings your character together into one cohesive body and allows the mesh to move with the bones after your character is animated.
  • Animate simple movements of your character to see how well your rig performs. You can use animation techniques like motion capture, forward kinematics, or procedural animation.
  • Fine-tune your character until it moves the way you want it to.

The process of rigging a character is all about refinement. It probably won’t look the way you want it to the first time, but with practice, you’ll be able to successfully bring 3D models to life.
