Textures (High Resolution):
4096x4096 Albedo 4096x4096 Base Color 4096x4096 Gloss 4096x4096 Height 4096x4096 Metalness 4096x4096 Normal (-Y) 4096x4096 Roughness 4096x4096 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.
