Creating a virtual reality game includes a number of unique challenges, but, as the Skyrim VR team can testify, VR's adaptation of an existing game is even more difficult. The main producer of Bethesda Game Studios, Andrew Scharfin an interview with VR Focus, shared some of the ways in which the development team had to modify or introduce functionality to make the game, old, of 6 years, natural and realistic.
Like many VR developers, the team knew that finding a way to handle the gaming movement would be a significant challenge. The original DualShock controller scheme can be used in the game and Scharf says the team has decided that the best way to present Skyrim as a free motion sickness experience is to give players additional control over things like the visual field.
The VR is a very personal experience, so it's important to allow players that flexibility: if you want to relax on the couch, you can play using the DualShock controller. We offer both teleport movement for those who are susceptible to motion sickness and direct movement for those who prefer fluid movements while optional FOV filters are available to relieve any discomfort while turning or moving fast.
Another challenge that developers have faced was limiting the same configuration of the PlayStation VR. While some virtual reality configurations for PCs offer multi-camera video, PlayStation VR only uses a camera and can only trace objects that appear in its visual cone.
So while players may want to turn their body to see something in the game, that movement would induce the VR not to track the PlayStation Move controllers used for the movement. After some adjustments, the team found that making some parts of the stationary IU helps to overcome this obstacle.
At first we found that it was a bit of a challenge that the players would wear the headphones and then turn around around to start moving in a random direction. A solution to helping players go the right way is to anchor important user interface elements, so if you can see the compass in front of you, you're heading in the right direction.
