Creating a Simple Scene

This step-by-step tutorial will guide you through instantiating and configuring a minimalistic, fully working scene in Unity using the Spatial Experience SDK.

Step-by-Step Implementation

Step 1: Create a New Scene

  1. Create a new, empty scene in Unity and name it according to your project's naming conventions.

Step 2: Add the Vehicle Prefab

  1. Right-click inside Unity's Hierarchy window.
  2. Navigate to holoride > Vehicle and click to instantiate the core vehicle tracking prefab.

Step 3: Configure the Main Camera

  1. Locate the Vehicle game object you just added in the Hierarchy.
  2. Locate the nested child game object: CameraRigParent.
  3. Drag your scene's Main Camera and place it as a nested child under CameraRigParent.
  4. Select the Main Camera and zero out its Position and Rotation transforms (ensuring scale remains set to 1, 1, 1).
  5. Note: If your camera has a legacy Simple Camera Controller component attached to it, remove it to prevent tracking conflicts.

Step 4: Add the Elastic Scene Generator (ESG)

  1. Right-click inside your Hierarchy window.
  2. Select holoride > Elastic Scene Generator to instantiate the core runtime generation pipeline controller.  

Step 5: Create an Elastic Graph Asset

  1. In Unity's Project window, right-click inside your assets folder.
  2. Select Create > holoride > Elastic Graph to compile a new graph asset.

Step 6: Name Your Graph

  1. Rename the newly created graph asset to a clear, recognizable identifier.

Step 7: Open the Graph Editor

  1. Double-click your renamed Elastic Graph asset to open the node graph visual editor.

Step 8: Assemble the Node Network

  1. Inside the Elastic Graph canvas, press the spacebar or right-click to open the creation context menu.
  2. Search and add the following nodes, connecting their ports in the exact order and setting the parameters shown below:  

Step 9: Reference the Graph in the ESG

  1. Expand your Elastic Graph asset in the Project window to expose its nested Elastic Scene Definition sub-asset.
  2. Select the Elastic Scene Generator GameObject in your scene hierarchy.
  3. Drag the Elastic Scene Definition sub-asset directly into the Scene Definition inspector reference field on the ESG component.

Step 10: Validate in Play Mode

  1. Click Play in the Unity Editor to watch the maps pipeline download data and procedurally generate a simple, beautiful elastic terrain around your vehicle!
