 There is another workflow known as the "`Specular Workflow`". In the metalness workflow the albedo map is used for both diffuse color and specular color. "`Specular Workflow`" uses a specular color map instead. In this workflow, the albedo map is the diffuse color, the specular map is the specular color, and you have a gray scale gloss map that is the same as the roughness map. The workflow is very similar to the old techniques used for making materials.
 
-This has been a brief introduction to PBR. In reality, it requires a significant amount of learning to implement correctly. Read the three part series of articles called, Physically Based Rendering, that can be found under the <<jme3#materials-light-shadow,Materials, light, Shadow>> topic for a more in depth explanation of PBR Textures. This is a must read for any serious jME developer.
