This is a project I worked on few years ago for the opening of Ubisoft's Might and Magic 7, made by Brunch Studio. I made all the stain glass shading, and I also made the lighting/compositing of almost all of this part.
It was originaly done with Maya, Photoshop and Vray. But as I lost texture files, I used Substance designer and marmoset to shad it again.
The Modeling was made by Johan Mai https://www.artstation.com/johanmai and Rémi Julien
