Comprehensive World Streamer 2 Setup for Unity

Objective:

Generate virtual grids that World Streamer 2 uses to manage and stream different scene segments effectively.

Why This Step is Important:

Virtual grids provide a structured framework for World Streamer to determine which scenes to load or unload based on the player’s position, enhancing streaming efficiency and world management.

Detailed Instructions:

  1. Access Scene Manager:
    • Navigate to:
      Tools > Nature Manufacture > World Streamer > Scene Manager
  2. Navigate to Streaming Layers Tab:
    • Within the Scene Manager, ensure you’re on the Streaming Layers tab.
  3. Select the Streaming Layers:
    • Ensure all desired streaming layers are correctly set up and configured as per Step 10.
  4. Initiate Virtual Grid Creation:
    • Primary Method:
      • Click the Split All Scenes Into Virtual Grid button located at the bottom of the Streaming Layers tab.
    • Alternative Method (If Primary Fails):
      • If the primary method doesn’t work, manually press the S button for each streaming layer to initiate grid creation.
  5. Monitor the Process:
    • Large Worlds: For extensive maps, the grid creation can take significant time.
    • Recommendation: Allow the process to complete without interrupting Unity to prevent incomplete grids or errors.
  6. Verify Grid Creation:
    • Upon successful creation, you should see new grid items within your Hierarchy.
    • Each grid corresponds to a scene prefix you set earlier, representing different segments of your world.
  7. Enable Debug Grids (Optional):
    • For visualization and verification, enable the Show Debug Grid checkbox for each layer.
    • This allows you to see the actual split and streaming areas in the Scene View or Game View, aiding in troubleshooting and optimization.

Troubleshooting:

  • Virtual Grid Not Appearing Correctly:
    • If the grid doesn’t generate as expected, ensure that:
      • All streaming layers have correct prefixes.
      • Objects are properly tagged or parented with the correct ObjectParent script.
      • Retry using the manual S button method.

Note:

  • Operational Order:
    • It’s advisable to perform virtual grid creation before adding dynamic world elements like rivers or terrain modifications to ensure accurate streaming segmentation.

Tips:

  • Regular Checks: After creating the virtual grid, periodically check the grid’s alignment and coverage, especially after making significant world changes.
  • Performance Considerations: Smaller grid sizes can offer more precise streaming but may increase management overhead. Balance grid granularity based on your game’s performance needs.
