Normal From Height Value 示例

This material graph sample demonstrates how to convert height values to normal vectors.此材质图表示例演示了如何将高度值转换为法线向量。

The Normal From Height Value node is accountable for conversion from a height value to normals.Normal From Height Value 节点负责将高度值转换为法线。

In this sample, a noise texture is used as a mask adjustable via the Coverage and Contrast parameters. The black-and-white mask is used as a blending coefficient for the Lerp node that performs linear interpolation between two normal maps and as the source height for the Normal From Height Value node converting the mask to a normal map.在此示例中,噪声纹理用作可通过 CoverageContrast 参数调整的蒙版。黑白蒙版用作 Lerp 节点的混合系数,在两个法线贴图之间执行线性插值,并用作 Normal From Height Value 节点将蒙版转换为法线贴图的源高度。

Finally, the result of two blended normal maps is added as the Detail Normal to the edge normals via the Reorient Normal Blend node and the resulting tangent-space normal vector is passed to the material.最后,通过 Reorient Normal Blend 节点将两个混合法线贴图的结果作为 Detail Normal 添加到边缘法线,并将生成的切线空间法线向量传递给材质。

The Albedo color is obtained from the corresponding parameter.反照率颜色是从相应的参数中获得的。
