  • Add any Zappar Tracking object from the Zappar menu.

  • Select on the Zappar camera game object and drag the tracking type (in your Hierarchy) into the “Anchor Origin’’ property.

  • Drag the echo3d script onto the tracking type game object and fill out the API key and entry ID details in the Inspector.

  • You can also drag the echo3D prefab onto the Zappar Tracking object in the Hierarchy to make it a child of the tracker for more control (if preferred).

  • Run in Play Mode and check scale, rotation and position to confirm it looks good.

  • Change Build Settings to WebGL.

  • Go to Build Settings > Player > Resolution and Presentation and select the Zappar player (Zappar for 2020+, or Zappar 2019 for anything older).
