Includes the following PBR (Physically Based) texture types (BOTH Metalness and Specular, perfect for Unity, Cryengine and UE4):
4096x4096 exterior diffuse 4096x4096 exterior ambient occlusion 4096x4096 exterior base color 4096x4096 exterior gloss 4096x4096 exterior metalness 4096x4096 exterior normal (-y) 4096x4096 exterior roughness 4096x4096 exterior specular
2048x2048 glass diffuse 2048x2048 glass base color 2048x2048 gloss 2048x2048 metalness 2048x2048 normal (-y) 2048x2048 roughness 2048x2048 specular
4096x4096 interior diffuse 4096x4096 interior ambient occlusion 4096x4096 interior base color 4096x4096 interior gloss 4096x4096 interior metalness 4096x4096 interior normal (-y) 4096x4096 interior roughness 4096x4096 interior specular
4096x4096 back ambient occlusion 4096x4096 back base color 4096x4096 back diffuse 4096x4096 back gloss 4096x4096 back height 4096x4096 back metalness 4096x4096 back normal 4096x4096 back roughness 4096x4096 back specular
Note about textures. The Normal maps are -y, this is fine for directx. If they look flipped, just highlight the green channel in photoshop and hit ctrl+i.
If the roughness and metalness look too shiny in say, UE4, you'll have to make sure they are set to linear. Just double click the texture and uncheck the sRGB box. You can also fix that by combining maps in an image editor like Photoshop.
UV's are mostly flat with a few pieces overlapping where necessary.
