I am currently exploring ways to implement an overlay menu on top of an A-FRAME scene.
A great example of what I am aiming for can be found on this website ->
By clicking on one of the tiles in the home menu, you will see that the previous scene is moved to the background and additional information appears in the foreground with a semi-transparent overlay.
If anyone could guide me in achieving this effect, I would be extremely grateful. Thank you! Cheers.
