You will find the button “Scene Preview (Beta)” directly under the editor where you edit your scenes. Once you’ve clicked on it, your work will be displayed as it would be with VR glasses. If you click on the image and keep the mouse pointer pressed down, you will be able to look around.
Attention: You cannot interact with your hotspots in the Scene Preview (Beta)!
You don’t just want to test one scene, but the complete interplay of your elements? If so, download the mobfish VR STUDIO app and try everything!
