Overview

BVA is a GLTF-based, cross-platform format that store 3D data and far more than that. The format can be supported by many tools such as various game engines, Babylon.js, Maya, Blender. The 3D data is stored in standard gltf scheme, other infomation that BVA provides were totally extended by Extension & Extra ,thus it doesn't break the gltf-standard, and this will continue as tradition, to make it can be opened directly by Windows 3D Viewer, Babylon.js, mainstream modeling software etc.

Any tools that support gltf will also support viewing or editing the 3D part data of BVA.

Technically, it can also store any kind of data, like Multi-Media, animation clips, Custom data, even scripting.

Furthermore, it might helps you create metaverse-like game like Roblox easily after integretion of user scripting, which was already on our roadmap.

Installing BVA

System Requirements

Working with UnityBVA SDK

As a 3D gltf compatible file format, BVA capable of loading 3D GameObjects regardless of the Engine's version, build target platform, which ease you the pain of creating the Apps that involve user-creation-contents (also known as UGC) . After all, creating such a format is not a piece of cake. A complete toolchain takes even more efforts.

Features

We believe that UGC will overwhelm the whole industry in the next decade and everybody will be encouraged to devote their effort on building the metaverse, let go of imagination and creativity.
