name	unity-build-size-optimization
description	Use to shrink player/install size: estimate build weight, find large assets, textures, Addressables, and unused or oversized content.

Unity build size optimization

Discovery

1. get_build_size_estimate — weight implied by build scenes
2. list_large_assets — files over N MB (default 5)
3. get_texture_meta — maxSize / compression hints per texture
4. get_addressables_info — whether content is remote vs local
5. list_ml_model_assets — ONNX/weights often dominate size

Checklist

• Cap texture maxTextureSize; prefer ASTC/ETC2 on mobile.
• Move DLC/optional content to Addressables remote groups.
• Drop unused scenes from EditorBuildSettings.
• Compress audio; streaming for long music.
• Keep ML models out of the main Data folder when possible.
