You can greatly reduce the size of your build removing unused textures and geodata files:
-
17 Earth styles plus Moon and Skybox maps are included with associated textures that ranges from 2K to 8K image files. Determine which styles you don’t use and remove the textures you don’t use from Resources/Textures folder. You could also remove custom shaders that you don’t use located in Resources/Shaders folders.
| Earth style | Textures used (*.PNG files located in Resources/Textures folder) |
| Natural (2K, Unlit) | Earth |
| Natural (2K, Standard Shader) | Earth |
| Natural (2K, Scenic) | Earth, EarthElevationMap, EarthClouds |
| Natural (2K, Scenic + City Lights) | Earth, EarthElevationMap, EarthClouds, EarthCityLights |
| Alternate Style 1 (2K) | Earth2 |
| Alternate Style 2 (2K) | Earth4 |
| Alternate Style 3 (2K) | Earth5 |
| Natural (8K, Unlit) | EarthHighRes8k |
| Natural (8K, Standard Shader) | EarthHighRes8k |
| Natural (8K, Scenic) | EarthHighRes8k, EarthElevationMap8k, EarthClouds8k |
| Natural (8K, Scenic + City Lights) | EarthHighRes8k, EarthElevationMap8k, EarthClouds8k, EarthCityLights8K2 |
| Natural (8K, Scenic Scatter) | EarthHighRes8k, EarthElevationMap8k, EarthClouds8k |
| Natural (8K, Scenic Scatter + City Lights) | EarthHighRes8k, EarthElevationMap8k, EarthClouds8k, EarthCityLights8K2 |
| Natural (8K) | EarthHighRes8k |
| Natural (16K) | Earth16K_BL, Earth16K_BR, Earth16K_TL, Earth16K_TR |
| Natural (16K, Scenic) | Earth16KScenic_BL, Earth16KScenic_BR, Earth16KScenic_TL, Earth16KScenic_TR, , EarthElevationMap8k, EarthClouds8k |
| Natural (16K, Scenic + City Lights) | Earth16KScenic_BL, Earth16KScenic_BR, Earth16KScenic_TL, Earth16KScenic_TR, , EarthElevationMap8k, EarthClouds8k, EarthCityLights8K2 |
| Natural (16K, Scenic Scatter) | Earth16KScenic_BL, Earth16KScenic_BR, Earth16KScenic_TL, Earth16KScenic_TR, , EarthElevationMap8k, EarthClouds8k |
| Natural (16K, Scenic Scatter+ City Lights) | Earth16KScenic_BL, Earth16KScenic_BR, Earth16KScenic_TL, Earth16KScenic_TR, , EarthElevationMap8k, EarthClouds8k, EarthCityLights8K2 |

By default, all textures are provided with TrueColor settings in Import Settings (uncompressed). Consider enabling the compression for the textures (ie. use Automatic Compression setting). Compressing the textures will greatly reduce the build size of your application but can also reduce the image quality a bit (mostly unnoticeable).
-
You may also remove some geodata files located in Resources/Geodata folder. For example, if you don’t use provinces, you can remove the provinces10 file. You can also remove the frontiers geodata file corresponding to a resolution you don’t use (countries110 is low definition vs countries10 which is high definition frontiers).
-
Scenic and Scenic Scatter textures (Earth, EarthHighRes8K and Earth16K*) have water mask baked into alpha channel. This is used for the specular shining effect. If you don’t use this option, you can switch the Alpha Import setting to None.
-
If labels are rendered in world space and tickers or markers are not used, you can switch the “Overlay Resolution” setting to “Not Used” to save an internal render texture.
