The baked map is now controlling the specularity of the surface as the musgrave was doing before.ДЇor complex shaders things becomes harder, you'll have to build a custom nodetree capable of exctracting the Specularity data on each passage (e.g. I added the same specular map to the Reflection Glossiness slot. Note how nice the bump of the material is now defined (the bump is the same, 0,01) Image 3. I added the specular map to the perpendicular slot of the Fresnel. To bake that data just use an emission shader picking the color from the cable that is going into the mix shader's input socket I just added reflection layer to the material, with 1,55 Fresnel. Where is black is Diffuse (no Specularity), where is white is Glossy (Specularity). In this case it's easy to understand that the amount of Specularity is equal to the values that go into te mix shader factor.

Let's consider a simple material made of a Diffuse and Glossy shader mixed with a musgrave texture: What you should bake is the data about where a surface is capable of reflecting light and where is not, and not how the light interact with the surface (Glossy color, Glossy Direct, Glossy indirect, Combined.) because these are the result of the render engine. These maps are used in order to give to the rendering engine the information about how the light should interact when hitting that particular pixel of the surface. Be kind and respectful, give credit to the original source of content, and search for duplicates before posting. Represents the amount of reflectivity a surface has. You can add a specular map to a 3D object in Photoshop by either loading one or creating a new one that you can then edit. I came to know about various new maps - like Metalness map, roughness map and specular map.

Bake the Specularity data, not the light interactionДЄccording to the Wikipedia, specular maps contains the valuest that: I was experimenting with Blender's new Principled BSDF node.
