Its important to understand the underlying concepts of a PBR system; however, at the end of the day you need to trust your artistic instincts. Here is a screen shot of View -> Zoom ->4:1. Red to metalness. Additionally, large scale AO should not be added directly to the specular pass, as occluded light isnt the same thing as a less reflective surface thats what the specular map defines. Rocks have reflection values and they are not 100% rough either. We will use an height map created with Section 14.8, "Simplex Noise" : Figure 17.176. Select the Layers tab.

Even the most basic diffuse maps have more than two tones, so for the third tone and beyond, the height map generator just takes over the wheel and drives over a cliff. Texture Conversion: Metalness -> Specular. Additionally, linear space rendering means we no longer have to color specular maps the opposite color of our diffuse to get a neutral white highlight, while energy conservation in the microsurface function (rougher surfaces will have broader highlights with a dimmer appearance as the light is dissipated over a larger area) removes the need to manually make rough areas dark and glossy areas bright in the spec map. Tutorial: How To Create A Seamless Texture in GIMP Roughness reflectivity. you can unpack the cube maps (aka; environment maps) from the "Fallout4 - Textures1.ba2" there at 'Data\textures\Shared\Cubemaps' then you will just have to pick one that suits the purpose.

PBR is essentially a holistic system of content creation and rendering, which can and often does have variances (generally shader models or texture input types) in actual implementation, depending on what tools or engine you use. Now more than ever, we can focus on replicating material properties rather than baking in specific lighting conditions. In practice, this means that much or even all (if your texture has only metals or insulators but not both) of either the diffuse or specular map will be wasted information, so the metalness workflow is usually more efficient. Texture Conversion: Metalness -> Specular The best way to combine the different channels together is to edit the layer group of the metallic and roughness layers in Photoshop and set the blending options to the specific channel they are going to go into. This means the specular map had to do double duty trying to represent both reflectivity and microsurface, while using a uniform glossiness value for the entire material.
