From Business Insider:
As detailed ina 2014 feature published in The Verge, Caroline Miousse, an Ubisoft level artist, spent two years poring over details of the cathedral to create as accurate a depiction as possible in the game.
"I made some other stuff in the game, but 80% of my time was spent on the Notre-Dame," she said at the time. The Verge's Andrew Webster wrote of Miousse's work on the cathedral: "She pored over photos to get the architecture just right, and worked with texture artists to make sure that each brick was as it should be."
This is the future of preservation. Along with many photos and videos hopefully Miousse's work will help to rebuild Notre Dame to its former glory.
