Plaza Floor

Decided to go with a cobble floor for the plaza area. One that i liked the most from my reference was from our London trip but the picture wasn't the greatest for creating a texture so some editing was in order

Original

Texture

Added some variation into the bump map to make the bricks uneven. Also the grout was very dark in the picture so I create a mask by painting out the grout areas and lay a texture underneath. This help the normals read better and make the cobbles look raised out of the ground slightly.

I made the edges of all the bricks catch more light in the specular also to enhance the normal map details.
