With the help of outsourcing, Abby's backpack was scanned first then modified and finalized in ZBrush to not only fit better but also avoid the patent issues. Her backpack went through several versions by adding extra pockets and straps to cater to the gameplay needs. Everything was textured in substance painter, sometimes photoshop. Images are screen-captured from the in-house game engine of Naughty Dog. Thanks also shading artists (Lauren Garcia and Waylon Brinck) for all the support and helping out with the shader.
