Build Size Treemap

Location: Tools -> Nexus Graph -> Visualizers -> Build Size Treemap

The Build Size Treemap provides a hierarchical view of your project’s storage footprint. Unlike a standard list view, the Treemap visualizes file size as area—allowing you to instantly spot the largest assets in your project relative to one another.

Features

1. Visual Area Rendering

• Area = Size: The larger the box, the larger the file.
• Color Coded:
  • Blue: Textures (Typically the largest candidates).
  • Green: Prefabs and Scenes.
  • Red: Audio and Media.
  • Grey: Scripts and Data.

2. Deep Project Scan

The tool scans your entire Assets folder structure. It is particularly effective at finding:

• Bloated Textures: 4K or Uncompressed textures that were imported accidentally.
• Hidden Data: Large serialized data files inside deep folder structures.

3. “Show Small Assets” Toggle

By default, the Treemap filters out insignificant files (<10KB) to reduce visual noise.

• Toggle On: To audit every single script and meta file (useful for verifying total file counts).
• Toggle Off: To focus strictly on optimizing build size.

Optimization Workflow

1. Open the Build Size Treemap.
2. Look for the largest blocks.
3. Click a block to ping the asset in the Project View.
4. Assess if the quality/compression settings are appropriate for the target platform.
