Best Practices for Baking Lighting in Unity
Effective baking lighting in Unity makes procedurally generated cities run better, especially on mobile. It’s key to mark static objects correctly and pick the right light types. Knowing these Unity best practices helps get high-quality lightmaps.
Setting Up Static Objects
First, mark objects as static before baking lighting. This tells Unity they won’t move, improving lighting calculations. Here’s how to set up static objects:
- Select the object in the Scene view.
- In the Inspector window, check the “Static” checkbox.
- Make sure colliders and renderers are set up right for lightmap generation.
Choosing the Right Light Types
The type of light you use greatly affects your scene’s look. Each light type in Unity has its own use and impact on performance. Knowing these options helps use baking lighting strategies well. Here’s a look at common light types:
| Light Type | Description | Best Use Cases |
|---|---|---|
| Directional Light | Simulates sunlight, casting parallel shadows. | Outdoor scenes or large open environments. |
| Point Light | Emits light in all directions from a single point. | Interior lighting, lamps, or small fixtures. |
| Spotlight | Illuminates a specific area, creating focused beams. | Theatrical settings or dynamic lighting effects. |
| Area Light | Cast soft shadows over a defined rectangular area. | Large spaces requiring soft, diffuse lighting. |
Using the right mix of static objects and light types leads to better lightmaps. Following these best practices boosts both look and performance in Unity’s procedurally generated cities.
Implementation of Lightmap Settings
Getting lightmap settings right in Unity is key for great lighting and good performance. It starts with setting the Unity lightmap resolution. This affects how detailed the lighting looks in your scenes. A high resolution means better lightmaps but can slow down mobile devices.
Finding the perfect balance is important for making procedural cities look great.
Configure Lightmap Resolution
When choosing the Unity lightmap resolution, think about your scene’s size and detail. A good range is 40 to 70 texels per unit. This captures detailed lighting without making the lightmap too big.
Also, consider the texture size. Bigger lightmaps can look better but use more memory. Try different sizes to find the best balance for your project.
Adjusting Bounces and Samples
Changing the number of bounces in lightmap settings can make interior lighting better. More bounces mean softer shadows and more realistic scenes. But, it might need more samples to keep performance up.
Sample counts between 20 to 50 usually work well. But, you might need to adjust these to get the lighting just right for your project. Finding the right mix of bounces and samples is crucial for procedural city lighting.
Using Bakery for Efficient Light Baking
