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”。 t >\sP Food<(!.> 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： /LD3Bb)O Normal Vector [9; @1I<x The Normal Vector is a vector in 3D space that is used to orient the projection J&xZN8jW plane for the irradiance map. The plane is defined to be perpendicular to the Z8|< %1Kge Normal Vector, and the irradiance incident on the selected surface is projected X6Ha C+P onto this plane. When the map is displayed, the normal vector is pointing toward Su#0 F0 you. ./YR8 #, Up Vector ^ ""edCs The Up Vector is a vector in 3D space that is used to orient the projection plane Tq1\ for the irradiance map. The plane is defined so that the Up Vector is parallel to the &hOz(825r vertical side of the plane. The irradiance incident on the selected surface is da$FY7 projected onto this plane. When the map is displayed, the up vector will point
G l~l toward the top of the screen.
