Then, we suggest that you should use standard specular lighting shader for your skin, in our experiment, the shader with unity ggx specular looks better than the others. We start to learn the details of what will be necessary for point lights and the ambient lighting. Dec 07, 20 creating bumped specular shaders as above is fairly straightforward because unity already comes with a bumped specular terrain shader you just need to specify a material that uses it in place of the default diffuse terrain shader. A higher value will make the specular highlight smaller and a lower value will make the highlight broader. Looking at the viking village it seems like unity uses the standard shader specular setup for everything, but you should be able to use the other shader as well, right.
