Depending on your project size and platform, it can be challenging to update all your assets smoothly! [echo3D](http://www.echo3d.co\) has made it easy to do this by simply using an API key. Assets are stored on the [echo3D](http://www.echo3d.co\) 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.
