Paste the Glossiness map into the alpha channel of the specular map in any 2D editing application.įinally, add the map to the Specular slot, the diffuse map to the Albedo slot, and the normal to Normal, and height to Height. There is no separate slot for Glossiness, and you will need to use the Alpha channels in either Albedo or Specular maps. When creating PBR material in Unity 3D using specular workflow, you must change the shader of the created material to Standard (Specular setup). The Diffuse map for the Base Color, and the Reflection for Specular and the Normal for Normal.

In addition, connect all the other textures as usual. This means black will be white and white will be black. To do this, use the OneMinus node to connect between the texture map and the roughness map, which will invert the image. When planning to use textures created for the specular workflow in Unreal Engine, you need to convert the glossiness map to the roughness map.

At other times you may only need specific maps, such as the Ambient Occlusion map or the Emissive map. In both of these workflows, you may not need all the maps in all situations, such as the normal map or the heightmap. Height (Displacement) Map – this map is used in the same way as the specular workflow.Normal Map – this map creates bumps and dents as in the specular workflow.This means that the black color in this map will have a sharp shiny finish, while the white has a fuzzy (matte) finish. It is also in grayscale and stores the same information yet is inverted. Roughness Map – this map works similarly to the glossiness in the specular workflow.The white translates into a pure metal surface, while the black translates to non-metallic surfaces. Metalness Map – saved as a grayscale this map controls the amount of reflectivity of a surface.

Albedo (Diffuse) Map – this map works the same way as the Specular Workflow.

The Metalness workflow utilizes the following maps:

Height (Displacement) Map – this map is saved as a grayscale which creates a larger group of convexities and creases which affect the objects mesh.

Similar to a bump map yet more advanced, the normal map is saved in RGB format, containing its information in XYZ axes.

Normal Map – this map determines the number of dents and bumps an object has.

Glossiness Map – this map controls the reflectivity of an object, whether the reflection of light will be blurred or sharp.

In its practical application the brighter the shade, the more light will be reflected.

Specular Map – defines an object’s shininess by using a greyscale map.

Albedo (Diffuse) Map – base color input, which is the most important map, giving information about the color of the object.

To create material in specular workflow you will need the following maps: Supported by many 3d applications and game engines worldwide each has its unique appeal to the individual user. PBR texturing’s most popular workflows are specular, and metalness workflows. PBR textures produce a higher quality of realness with greater variations of lighting, producing flexibility and predictability in the final product. What are PBR Textures? PBR, or Physically Based Rendering, is a model of shading used in computer graphics that more closely mimics the flow of light in the real world.
