Decentraland, the open standards-based social VR world project which raised $25 million through an Ethereum ICO last year, just Alpha launched its SDK for creating "scenes", i.e. "the collection of 3D objects, textures, and audio rendered on one or more LAND parcels." Up until now, some have raised hackles that Decentraland feels more like virtual tulip mania, than a virtual world. Now, however, developers can create content for it -- though for now, accessible only by one user at a time:
This release of the SDK allows you to create static and dynamic singleplayer scenes. In other words, you can build a 3D experience, with or without interactive components, that one user can interact with alone. We have included the ability to build experimental multiplayer scenes where multiple users can interact with scene components and each other. We’re still fine tuning this functionality, and will release more robust multiplayer support in a later version of the SDK.
Lack of multiplayer functionality, by the way, is one of several reasons Decentraland didn't make the cut in this infographic on metaverse-like VR platforms. But at the rate the Decentraland team is adding features, that chart will need updating quite soon.
