There are vertical black lines into the optic of the pimax.
Why?
As far as I am aware it is the defogging system. If you look around the forum, it has been answered by support. There is a flash of light then the lines are more visable and disappear. To clear and condensation.
To be honest it seems to work.
Hmmm i have no fog with my homido cardboard.
I don’t think it’s a great idea because you see the lines or shadows.
what are using the oculus and the vive?
I guess your cardboard device is not so enclosed, maybe they put them there so that when all the people who moan constantly run out of things to moan about,they can see the lines and moan about them.
Like a Easter egg.
