Low Poly Game Models
Low poly 3D modeling is a technique used in game development to create 3D models with a relatively small number of polygons or vertices compared to high-poly models. This approach is essential for real-time applications like video games because it helps optimize performance while still delivering visually appealing graphics. Here are the key steps and considerations for low poly 3D modeling for games:
Low poly 3D modeling for games is all about finding the right balance between visual quality and performance. It’s important to optimize your models effectively while still delivering an engaging gaming experience. As you gain experience, you’ll develop techniques and workflows that suit your specific project needs.
Low Poly 3D Modeling for Games, The usage of polygons should be limited maintaining the outer shape of the body which is the most important factor to be kept in mind while working on a low poly model.
The model should follow the shape of the high-resolution model as much as possible. You just have to take care of the boundaries; else, the normal map is going to take care of all the details inside.
While making a character in Low Poly 3D Modeling for Games:
- Ensure that the geometry matches the existing skeleton, from the big parts down to the details (fingers).
- Choose a pose that suits the range of emotions that the character needs to achieve.
- To improve the general deformation of the model, make sure that all the joints (arms, shoulders, legs) are slightly angled. It is necessary because due to slight angles it becomes easier for the IK handlers to read the postures of the models and the way they will be animated further.
- The joint should never be stretched to its maximum, it should be a natural in-between pose.
- The pose of the character differs according to the requirements of the character, in general, it is advisable to give a natural and comfortable pose to a character.
To make the model work correctly – Ensure the following:-
- The characters geometry should be connected to a skeleton and should be exported in the .chr
- IK limits should be set up correctly.
- The character geometry should face the positive y-direction in 3ds Max or the positive z-axis in XSI and Maya. The rotation values must be 0/0/0.
- The character geometry’s pivot position is at 0/0/0.
- Faster to render: Low poly models require less processing power to render, which means they can run on older hardware and mobile devices. This is especially important for mobile games, which need to run smoothly on a variety of devices.
- Smaller file size: Low poly models have a smaller file size than high poly models, which means they take up less storage space and can be downloaded faster. This is important for mobile games, which need to be downloaded quickly and easily.
- Easier to animate: Low poly models are easier to animate than high poly models. This is because they have fewer polygons, which means there are fewer vertices to move around.
- Unique aesthetic: Low poly models can have a unique aesthetic that is often described as “retro” or “minimalist.” This can be a good way to make your game stand out from the crowd.
Of course, there are also some drawbacks to using low poly game models. They are:
- Less detail: Low poly models have less detail than high poly models, which means they can look less realistic.
- Limited flexibility: Low poly models are often less flexible than high poly models, which means they may not be able to be used for all types of characters and objects.
Here are some tips for creating low poly game models:
- Start with a simple base mesh: When creating a low poly model, it is important to start with a simple base mesh. This will help you to keep the model’s polygon count low.
- Use texture maps to add detail: Texture maps can be used to add detail to low poly models without increasing the polygon count.
- Use normal maps to add depth: Normal maps can be used to add depth to low poly models without increasing the polygon count.
- Use baking to create shadows and lighting: Baking can be used to create shadows and lighting for low poly models without increasing the polygon count.
- Use shaders to create special effects: Shaders can be used to create special effects for low poly models, such as reflections and glowing materials.
