its panoramic- which means there is not 1 screenshot there. every picture you saw there there is formed by at least 6 different picture. thats why field of view is large.
For merging im using photoshop.
This costume is looks amazing exept Mantle. I mean look at this :
runing animation on this mantle looks like Quasimodo from Notre Dame de Paris .
I really liked this costume please fix the animation.
