How To Integrate echo3D Into a Unity Project — Free Tutorial

Updated: May 27

Depending on your project size and platform, it can be challenging to update all your assets smoothly! echo3D has made it easy to do this by simply using an API key. Assets are stored on the echo3D cloud and called at runtime so your experience runs smoothly and faster, every time and everywhere.

In this tutorial, you will modify an existing Unity project to utilize echo3D. The music making icons will be swapped out in echo3D.

  • Clone this repo, see the full README here

  • Import the Unity SDK

  • Add the assets to the echo3D cloud from the Unity ‘Models’ folder

  • Uncheck the Security box in your console

  • In Unity, open MusicScene

  • Drag the echo3D script onto the Drum, Piano and Guitar

  • Add the API key and entry ID for each object in the Inspector

  • In the Hierarchy, uncheck the box for the Sprite Renderer for Drum, Piano and Guitar

  • Press Play in Unity to see where the 3 assets show up in the scene so you can modify the metadata in the console

  • Adjust the metadata in the echo3D console as follows so the assets appear within the colliders: Drum: scale: .1/ xAngle: 90/ zAngle: 180 Piano: scale: .1/ xAngle: 90/ zAngle: 180/ x: -7/ z: .4 Guitar: scale: .1/ xAngle: 90/ zAngle: 180/ x: -14/ z: .4


  • Press Play in Unity and click on each instrument to play and stop music while the assets stream from the echo3D cloud 🎉.
