The Pixyz Plugin for Unity lets you build and use imported models with Materials, Meshes and Metadatas on any target platform available in Unity.
Also, it is possible to build Windows standalone applications that can import PXZ files at runtime.
To do so, you'll need to enable "Windows Standalone" under Edit > Preferences > Pixyz to automatically include the Pixyz binaries (~500mb) with your build.
NOTE This option is only available if your license is valid for runtime use. See Licensing Policy for more information.
Please check Importing at Runtime to see how to use Pixyz to import at runtime.
