Since I'm impatient and couldn't find a better way to draw fractal lines the way I wanted, I just shook my hand a little as I traced my outline to give my coast a jagged appearance. Repeat for the green (roughness), blue (AO) and alpha channel (metallic) images. 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. Why is it important that Hamiltons equations have the four symplectic properties and what do they mean? 1 Answer Sorted by: 2 For Specular based shader system you need: specular texture (effects the reflection color) glossiness texture (effects the reflection sharpness) In Cycles is used roughness, which is inverse of glossiness In Blender Internal it is called hardness For Metalness based shader system you need: Step 2: Fill The Document With A Light Brown.

In the end, a normal map does create the illusion of depth detail on the surface of a model but it does it differently than a bump map. Create a Normalmap directly inside your browser! Material has a specific Material Type as with previous versions of Trainz. One way is to use the Brush tool and select a brush that has a lot of texture to it. 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. A normal map uses RGB information that corresponds directly with the X, Y and Z axis in 3D space. Specular maps are used to define the shininess/highlight on a surface.

Smoothness and roughness are two ends of the same measure, normally using a scale of 0.0 - 1.0. With gloss maps, bright values typically define smooth/glossy surfaces, while roughness maps typically use bright values to define rough/matte surfaces. The metalness workflow on the other hand, uses the albedo map to define both the diffuse and reflectivity content and the metalness map to define whether the material is an insulator or a metal. A dusty rock is going to be very rough, maybe even completely rough, but a smooth rock from a river might actually be pretty polished and pretty glossy. The page you were looking for does not exist. One last thing, is it diffuse or albedo? - invert the alpha channel. Then we need to launch the NormalMap plugin, which you can find in in the same area as the Bump Map filter.
