Is it mandatory to have VR glasses to create a VR project? Or can it be done without?
You can do it without using VR simulators, but depending on your ambitions being able to experience your creation is very important
You can simulate the output of the glasses but you won’t be able to tell from that if it actually looks right in VR. I’ve had things that looked great on a monitor that looked just awful in VR. You also won’t be able to test and optimize anything related to the experience.
