Requirements

Supported Unity Version

  • The only version of Unity we currently support is 2017.2.0p4

Single Scene

  • Experiences should consist of a single Unity scene. Only this scene will be included in the .limapp package and attempting to load other scenes from your Unity project will not succeed.

Minimum FPS

  • Experiences must maintain a framerate of at least 60fps on all supported devices, in line with requirements for the GearVR and Google Daydream platforms.

Ending Your Experience

Add

using Liminal.SDK.Core;

Then call

ExperienceApp.End();

To end your Experience

Ensure these Settings are Applied

Single Pass Rendering

Edit > Project Settings > Player > Android > XR Settings > Stereo Rendering Method = Single Pass (Preview)

Avoid / Do Not Use

Programming Language

  • Liminal SDK is intended for use with C# scripts. Scripts written in UnityScript/JavaScript and Boo are not supported.

Global State

  • Do not change the global state of the project within your scripts.

Timescale

  • Do not change the timescale. It should always be set to the default value of 1.

Unsupported Plugins

Plugins can be used as normal, but imported scripts must comply with these requirements in the same way as your own scripts. When choosing whether to use a plugin, review its code as well as its terms and conditions carefully.

Licensing

  • We discourage using licensed plugins.

Known Incompatibility

  • Curvy
  • Postprocessing

[Serializable] Classes

  • These classes need to have a constructor without an argument if they use constructors.
  • Data may be lost during instantiation if the object is not in the scene.
  • Serializable classes that reference a scriptable object need the scriptable object to have [PreferBinarySerialize] attribute

Static Variables

  • These will be initialised the first time the experience is loaded, but not necessarily before each time it is run. If the Experience depends on static variables, ensure these are correctly initialized, for example from a listener for the ExperienceApp.Initialize event

DontDestroyOnLoad

  • Do not call DontDestroyOnLoad() anywhere within your scripts.

Ownership Rights

You must own the rights to all the content within your submitted Experience or they must comply with the conditions of the original content owner.

Some things to consider. Are you using…

  • Copyrighted music
  • Logos or direct references to brands
  • 3D models and assets must comply with re-use for commercial purpose
