They only have differences in map sizes and grades of the bump.───它们只在地图尺寸和凹凸的程度上有所不同。
Surface omni - as this source illuminates the surface we put a usual shadow map in Shadows bookmark, so as the shadow from the bump on those planet areas where it will take place is not so sharp.───表面泛光灯——作为星球表面的照明光源，我使用普通的阴影贴图，这样由行星凹凸不平的表面导致的阴影就不会那么锐利。
Without the bump map, the surface would be displaced during the render, but the shading information would be unaffected .───没有凹凸贴图，表面将在渲染时被置换，但着色信息将不产生影响。
For the skin I used mentalray sss shader. So I had made a diffuse map, epidermal map, bump map and specular map for her skin.───对于皮肤，我用了mentalraysss材质。因此我为皮肤分别做了一张
A bit like 'Spotlight', except that instead of merely exposing part of your desktop, it creates a bump map from it.───有点象“聚光灯”，只是它除了照亮您的部分桌面，还生成一幅凸起的图案。
If you fill a bump map with a uniform, gray color, it corresponds to a perfectly flat surface.───如果你统一的填入一张凹凸贴图，灰色，它相当于一个完整的平面。
The Bump map now allows you to create the leather texture.───凹凸贴图可以让你创建皮革的纹理。
Now we have to create a bump map, and a shine map.───现在我们必须创建一张凹凸贴图和一张发光贴图。
Now for the bump map, take the original petal, desaturate it and take the levels down to something like this.
Every texture now has its own unique colour map, bump map, specular and, in some cases, even have a normal map.
I use a specular map, reflexion map, and bump map(pictures below from left to right) for her skin, too.
