Short description

Unity’s VR Open source solution, which is a cross-platform game engine that can be used to create 3D and 2D games, as well as interactive simulations and other experiences. The engine has been adopted by industries outside video gaming, such as film, automotive, architecture, engineering, education, construction, and the United States Armed Forces.

VR Builder helps you create interactive VR applications better and faster by setting up a scene paired to the VR Builder Process. Through the VR Builder process, you can define a sequence of actions the user can take in the scene and the resulting consequences.

You can easily edit a process without coding through VR Builder’s Workflow Editor. The Workflow Editor is a node editor where the user arranges and connect the steps of the process.

The behaviours and the conditions are the “building blocks” of the VR Builder. Each step is a different node and can include any number of behaviours, which make things happen in the scene.  

Likewise, a step will have at least one transition leading to another step. Every transition can list several conditions that have to be completed for the transition to trigger. For example, step B can be reached only after the user has grabbed the object specified in step A.

Since VR Builder is open source, you can always write your own behaviors and conditions as well. Behaviors and conditions can interact only with process scene objects. These are game objects in the scene, which have a Process Scene Object component on them.

This makes it very easy to start from some generic assets and build a fully interactive scene.

However, these solutions have an important knowledge to acquire and necessarily some materials’ recommendations to run Unity system requirements:

  • OS: Windows 7 SP1+, 8, 10, 64-bit versions only; Mac OS X 10.12+; Ubuntu 16.04, 18.04, and CentOS 7.
  • GPU:Graphics card with DX10 (shader model 4.0) capabilities.
  • RAM:8Gb but 16 Gb is recommended to use Unity


Elements of innovation:

A VR Builder allowing the made of realizations, scenes, and behaviours without coding.

Target groups

  • Any teacher that wants to create an VR game or an educational scene
