This bridge was created as a part of the environment package for a stylized action side scroller prototype. The model was built in Maya and the diffuse map was hand painted in Photoshop CC. From there the diffuse map was brought into Allegorithmic's Bitmap2Material to generate the normal map. Both the diffuse base and the normal map were then brought into Allegorithmic's Substance Designer to create materials to be used with a PBR shader leveraging diffuse, metallic, roughness and normal maps. The final renders here were created in Marmoset Toolbag 2 utilizing an IBL environment.
