ModelImporter 中用于计算法线的平滑信息的来源。
描述 Unity 如何计算边缘具有硬法线还是平滑法线(使用平滑组或面之间的角度)。默认情况下,如果存在平滑组,Unity 将使用平滑组。如果不存在,则使用角度。
另请参阅:ModelImporter.normalSmoothingSource、Mesh.normals。
PreferSmoothingGroups | 如果模型文件中存在平滑组,则使用平滑组,否则使用角度(默认)。 |
FromSmoothingGroups | 使用平滑组来确定哪些边缘是平滑边缘,哪些边缘是硬边缘。 |
FromAngle | 使用相邻面之间的角度来确定边缘是平滑边缘还是硬边缘。 |
None | 不创建硬边缘。 |
