Unity Packing Volume Optimization

Posted on Edited on In Waline:

Recently, I read some articles about Unity volume optimization solutions and Unity’s official doc to summarize

Resource optimization

  • Compress the image size, reduce the size of the texture with low accuracy requirements, and select the appropriate compression algorithm according to the needs of the platform.
  • Turn off picture minimap and A channel.
  • Sprite Atlas (formerly Sprite Packer), which packages multiple maps into one map
    Mesh Optimization: Set Mesh Compression to Low, Medium or High
  • Use Prefab instead of scenes
  • Use Addressable to unpack resources to CDN download

Code optimization

  • Set iOS Stripping Level to Use micro mscorlib__ on Mono or enable Strip Engine Code on IL2CPP
  • IL2CPP Enable Managed Code Stripping
  • Do not use the System.dll method (this method requires refactoring the code to replace all used places)
  • Remove unnecessary code dependencies
  • API Compatibility Level 选择 .NET Standard 2.0

Packaging optimization

General purpose

  • Turn off static resource pooling
  • Packaged version selection Release
  • Build Settings Compression Method Release时选择LZ4HC

Android

  • If not necessary, reduce the supported architectures of Android (for each additional architecture, an additional set of symbol tables will be added, and 50 + MB will be extracted)
  • Publish Settings Launch Minify

Product optimization

iOS

  • Close bitcode
