The photogrammetric survey was carried out with 3DF Zephyr in two parts, one for each face, and later aligned and fused in Blender, resulting in a 3D model of 387K tris. Performed a highly optimized manual retopology in Blender thus obtaining a LP model of just of 3K Quads.
Diffuse, Normal and Ambient Occlusion maps were baked in Blender and tweaked in Photoshop, in addition to creating the Roughness and Metallness maps there too.
