Multiple file types are also included in the .zip file so you can open this in just about any 3d program or game engine.
Display images were rendered in Marmoset Toolbag.
Normal maps were baked from a high poly model.
Includes the following 3d file types:
Max 2014 file Maya 2014 file .FBX 2014 .OBJ 2014
Includes the following PBR texture types (BOTH Metalness and Specular, perfect for Unity, Cryengine and UE4):
4096x4096: Ambient_Occlusion 4096x4096: Base Color 4096x4096: Diffuse 4096x4096: Gloss 4096x4096: Normal Map 4096x4096: Roughness 4096x4096: Specular 4096x4096: Metalness 4096x4096: UV Map
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.
