Varwin SDK

What this is

SDK (software development kit) is a set of development tools that allows creating apps for certain program suite. Varwin SDK is a set of tools for creating content (objects, scene templates) for Varwin in the Unity development platform. In order to work with Varwin SDK, Unity ver. 2018.4.27f1 has to be installed on your PC.


Varwin SDK comes as a Unity archive file (VarwinSDK.unitypackage). The link for downloading the file is attached to the letter you received while installing the Varwin RMS.
