向量vectors设置问题，不清楚如何设置Normal and Up Vectors，你可以在Irradiance/Illuminance Options中选中"Automatically calculate Normal and Up Vectors”。 hJ Sv x pL u5x< 另外，分析图的颜色和项目也可以在Irradiance/Illuminance Options中设置。
站长说的很对，补充一下： -'O|D} Normal Vector G(?1 Urxi The Normal Vector is a vector in 3D space that is used to orient the projection _8 r'R plane for the irradiance map. The plane is defined to be perpendicular to the ]i075bO/ Normal Vector, and the irradiance incident on the selected surface is projected xKUWj<+/ onto this plane. When the map is displayed, the normal vector is pointing toward 0,-]O= you. iOfO+3'Z_U Up Vector ! \| The Up Vector is a vector in 3D space that is used to orient the projection plane %h(%M'm? for the irradiance map. The plane is defined so that the Up Vector is parallel to the :Z/\U* 6~ vertical side of the plane. The irradiance incident on the selected surface is )n"0:"Ou projected onto this plane. When the map is displayed, the up vector will point 9BP'[SM%), toward the top of the screen.
