VR Questions – Camera scale, Menu, Object Rotate

Hello,

I am trying to make our App work in VR and am running into a coupe issues/ have some questions about capability.

1. When the VR app loads, The object is huge and you are inside of it. How do i set the scale of the world in VR?
2. Can I use the same HTML menu in our standard app in the VR space?
3. I would like to be able to click the objects and rotate around the object or have the objects rotate. even better if possible it would be ideal to have the object tied to one of the controllers and the movement of it related to that.

This is our app: https://apeironweapons.com/wp-content/uploads/verge3d/4385/index.html

Thanks
