To add an object into your scene, navigate to the “Objects” tab on the "Lecturn" panel.
Select an object from the list and it will appear in an appropriate location within the current environment.
To add a new object that's not on the list, click on “Import file” to select one.
If you select a model, a context menu will appear with some options.
In VR mode, you can use the grip buttons on your controllers to move, rotate, and scale the object. If you're stuck, check out the VR controllers guide here.
In desktop mode, you will have the option to select “Transform”.
A further menu will open and you can choose from the same options that you can perform in VR – move, rotate, and scale.
The next option is to duplicate an object. This will create an exact copy of the object nearby to the current one to move, rotate and scale.
To delete the object from the scene, select "Remove Model".
