Unity and Web-XR
Adding Web-XR to unity using Mozilla Mixed Reality Plugin.
I found out that you can export XR with Unity using the WebXR exporter from moz:illa Mixed Reality. Pretty straight forward and easy to implement. Of course there are some limitations and advantages towards using this method, but I’m posting it for your consideration.
When importing the package, I had problems with the original materials with Unity version 2018.4 & 2019.3, but that was only with the sample scene.
Here you can check out the simple diorama Unity package example that I created. This is the GitHub repo for the plugin with all instructions on how to implement.
