Large Scene Workflow

Managing performance in large, open-world scenes requires a different approach than small indoor levels.

Step-by-Step Strategy

  1. Scene Partitioning: Use Unity’s Sub-scenes or Addressables.
  2. Bulk LOD Generation: Use Performance Pro to select all environmental meshes and generate LODs in one batch. This is critical for reducing polygon count at a distance.
  3. Occlusion Baking: For areas with high occlusion (cities, forests), use our Occlusion Helper to set up the bake settings correctly.
  4. Shadow Distance: Large scenes suffer from shadow rendering costs. Use Performance Pro to audit shadow distances and culling.
  5. Texture Streaming: Ensure your textures are set up for streaming to avoid loading massive 4K textures for distant objects.

Pro Tip

Use the “Scene Hierarchy Scan” to find deeply nested objects that are breaking batching. Flat hierarchies are generally faster for Unity to process.
