Furthermore, more and more companies and hobbyists create 3D models using AI technologies and effectively implement them in games. This article will teach you about the relevant substance of 3D models in games. Begin to explore the world of 3D models!
What is 3D Modeling for Games?
3D modeling for games is the process of creating 3D digital objects, characters, and environments that can be used in video games. Depending on the game's art styles, artists and developers built realistic and stylized 3D modeling using professional software. The process begins with conceptualizing the design through sketches or digital art, providing a blueprint for the model's form and function.
Then, artists use an array of industry-standard software to sculpt high-poly models that capture intricate details and textures. After careful modeling, 3D modeling for games transforms creative concepts into dynamic, interactive elements that enhance the overall gaming experience.
Quick Guide for 3D Modeling: Process and Tools
Following the quick guide allows you to ensure that every step builds on the previous one, resulting in efficient workflows and high-quality 3D models.
- Concept and Design: Begin with complete concept artwork and brief design
- High-Poly Modeling or Sculpting: Use detailed meshes or sculpts to capture all of the required information.
- Retopology: Reduce the high-poly model to a game-ready version with optimal polygon count.
- UV Mapping: Unwrap the 3D model to create a 2D plan for texturing.
- Baking: Move details from the high-poly to the low-poly models.
- Texturing: Paint the model and create textures.
- Testing: Add the asset to the game engine and evaluate its appearance as well as its performance.
You will use the following tools during the 3D modeling process:
- Blender: It is a free and open-source 3D creation suite that offers robust modeling, sculpting, animation, rigging, rendering, and compositing tools.
- Maya: Maya is a powerful 3D animation Autodesk software used by specialists and famous studios, which is used for modeling, rigging, animation, and rendering.
- 3ds Max: 3ds Max is another Autodesk software that is known for cutting-edge functions and support for high-level animation workflows, and is commonly used by AAA games
- ZBrush: ZBrush is perfect for sculpting, detailing, and creating high-res models, which has perfect functions like Brushes, ZRemesher, DynaMesh, Sculptris Pro, and Polygroups.
- Meshy: Meshy is an innovative AI tool for modeling artists to create 3D models efficiently. Just upload an image or input some words on Meshy, which means you will get 3D models in a minute without any tedious work. What's more compelling is that Meshy is the only 3D tool in A16Z's popular tool survey.
How to Make 3D Models for Games
Step 1. Concept and Reference Gathering
You have to be exactly clear about what you want to create when you start the digital manufacturing process. Get reference pictures of the thing or figure you're copying showing its style, traits, and dimensions. Drawing your ideas can also help you refine your concept and offer a map for you during the 3D modeling process.
Step 2. Create Your High-poly Models.
And now, you can create your high-poly models with software like Maya, 3ds Max, Blender, or Meshy. At this stage, you should detail your final product to create something that looks engaging without worrying about the polygon count.
Step 3. Retopology for Game Optimization
Retopology, which means you have to reduce the number of polygon counts in your model yet manage to keep as much detail as possible because of performance restrictions. This can be done manually or with the help of specific software tools.
Step 4. Flatten 3D Models into 2D Images(UV wrapping)
UV wrapping is the process when you project your 3D model onto a 2D plane to create a template. You can think of it like unfolding a box to lay it out flat. Because it determines how the 2D texture maps will wrap around the 3D model, this stage is absolutely vital for texturing.
Step 5. Add texture to your models.
Texturing your model with color and detail is crucial. Software like Photoshop or Substance Painter allows you to hand-paint textures; alternatively, you might make your textures using images and procedural techniques. Giving your model materiality, depth, and realism will help it to make sense.
Step 6. Rigging for Animation
Rigging is the process of adding a skeleton to your model, allowing it to move. By adding bones and controllers, animators can pose and animate the character or object. While it can be tricky, rigging is essential for making a model move in a game. To create smooth and visually appealing assets, always keep your game engine or platform's requirements in mind.
Step 7. Integration into Game Engines
After rigging and animation, the 3D model is brought into a game engine. This step allows the model to interact with the game world, reacting to player inputs and the environment. Proper integration is key because it ensures the model runs smoothly in real-time, enhancing the overall gameplay experience.
Key 3D Modeling Techniques You Have to Know
After introducing the 3D modeling procedure, let's discuss the key techniques that artists inevitably utilize.
- Polygonal modeling: Polygons are utilized to create 3D objects, which serve as building blocks for the 3D model's structure.
- Digital sculpting: it is the technique of shaping virtual objects to get the desired appearance for a character, beast, or other element.
- NURBS: A mathematical method for defining curves and surfaces that uses weights, knots, and control points to create 3D models.
- Procedural modeling: Rather than modifying individual elements, it creates 3D models using algorithms and parameters.
Okay, now that you've seen how 3D modeling is utilized in game development, let's look at how to make 3D models for games.
7 Main Types of 3D Models for Game Production
There are seven major categories of 3D modeling for game production; this article serves as a foundation for beginners to understand these seven types of modeling. Although you are not a 3D modeling artist, you should learn about the numerous types of 3D modeling. Choosing a suitable one will arrange images to appear as lovely as possible, so you must determine which one is best for your tasks.
Character Models: Character models are commonly used in video games, and they include everything from human-like characters to fantasy monsters, robots, and animals. Typically, they are decorated with intricate textures and wired for motion to give movement and expressiveness.
Environment Models: This includes objects like buildings, terrain, plants, and other features that fill the game world. They bring the scene to life and help create the game's atmosphere. Without them, the world would feel empty and less immersive.
Weapon Models: Especially for shooters and action adventures with weapon customization, rely heavily on weapons like guns, melee tools, explosives, or magical items. These models need to look realistic and often include animations for actions like firing, reloading, or handling.
Vehicle Models: Many games involve driving, flying, or other kinds of transportation that require car models. 3D objects such as vehicles, planes, boats, future spacecraft, or legendary mounts should be visually appealing and practical, with animations for movement and interaction, to captivate players.
Prop Models: Although people may be ignorant of prop models, these minor features provide detail and realism. These props can be furniture, tools, containers, decorations, or anything else that the characters can interact with. In addition, they can serve as backdrop pieces.
Special Effects Models: These models are used for explosions, fire, smoke, sparks, magical spells, and environmental effects like weather. Often animated, they play a vital role in making a game's visuals more dynamic and immersive.
UI Models: UI models aren't part of the game world itself, but they're essential for creating menus, HUDs, icons, buttons, and other interface elements players use. These models are crucial for making games more user-friendly and enjoyable to play.
Tips on 3D Modeling for Games
Choose the Right Software
Selecting the most suitable software is integral to streamlining your 3D modeling workflow for games. Different tools offer unique features tailored to various modeling tasks, from creating complex environments to fine-tuning character animations.
