I used alot of reference images of the `ponte rotto` in Rome since it was also destroyed or broken.
|Bridge in the level York|
After a rough whitebox version of the bridge i started with all the pieces i need and constructing them in 3ds max and Zbrush. When i was done i assembled all together and formed the big pieces out of it. The tricky stuff was the destroyed bridge, but i managed to fit it into the bridge level design. After completing all the bridge pieces i did the nice texture painting and rendering, since Ryse used a PBS (physical based shading) it was kind of easy to follow the rules for diffuse and gloss setting.
The Bridge was then finished after 4 weeks with all pieces and LODs.
