Polygon Streaming Unity SDK

This page details basic information about using VIVERSE Polygon Streaming with Unity.

---

Unity Engine Plugin

Polygon Streaming models can be added to Unity Engine based projects with the use of our Unity Plugin, being able to stream multi-million polygon models streaming from the cloud into your projects and build for desktop, mobile and VR headsets.

Installation

1

Open Package Manager inside the Unity Engine - The Plugin should ONLY be installed via Package Manager and not copying inside the project’s folder, since it also need to automatically install dependencies:

Select Window > Package Manager to launch the Package Manager module

2

Press the + button and choose Add Package from tarball… and select the downloaded .tgz file.

Select the "Add package from tarball..." option before selecting your .tgz file

Verify the Package was Installed

1

If everything went correct, the package should now be visible under the Packages list in the project panel

Packages list should now include the package you selected

Handling Stream Controller destroying/disabling edge cases Free up resources when hiding/disabling models Hotfix light probe usage. Quality Priority now works only with integer numbers and follow the following logic: 0 = Highest priority. 1 = Lowest priority. 2 or more = Higher priority than lower number, but still lower priority than 0.
