Some simplified dropdown options for various Vr devices would be great to remove the need to fiddle with eye distance and all that.
As I understand the matter, VR devices cover a range of interpupillary Distances.
In case of gear VR for example it would be 55mm-71mm.
For every person there is a perfect dstance and I did come across a list of "media values" that work well for the vast majority of people.
While a drop down list with the distance boundaries would be nice, it's counterproductive.
If you wish to fake or do some extra stereo trickery, like doing some vertigo style pupil dilation or drug-VR experience you would want to push it further out then allowed.
It's the artist's job to knw what device he works with, getting tables on eyedistance harcoded would be more trouble than worth.
