Sinespace is a free-to-play massively multiplayer online Unity 3D-based platform created and published by Sine Wave Entertainment. It enables users to create and sell 3D content and interact with others as 3D avatars. It was beta launched in November 2016 and teamed up with Unity to make its SDK available in the Unity Asset Store in March 2019. It supports Oculus Rift, HTC Vive and Windows Mixed Reality headsets, but is also accessible through PC, Mac, Linux, and Chrome web browsers.[1]
