I was recently working with a streaming audio tech created by a former colleague. Jukebox Audio lets you create playlists in the cloud & then stream the audio in your game or project. Integrating the SDK can take an hour.
I was interested to use some music by some friends in a band called Montefiori Cocktail. The idea is the music is playing like a radio station as drive around having a casual drive in a countryside.
After watching some videos & reading some documentation, I was able to create some terrain using the powerful tools in Gaia. I can really recommend this asset. You can work with height maps & create a terrain.
