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”。 V_f}Y8>e # D"TY-$.= 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： 4+&4 Normal Vector A[20ic The Normal Vector is a vector in 3D space that is used to orient the projection I*c B
Ha plane for the irradiance map. The plane is defined to be perpendicular to the F-i`GMWC Normal Vector, and the irradiance incident on the selected surface is projected g/H:`J onto this plane. When the map is displayed, the normal vector is pointing toward lGHU{7j\ you. "fWAp*nI3t Up Vector /G)Y~1ASA% The Up Vector is a vector in 3D space that is used to orient the projection plane \-(.cj)? for the irradiance map. The plane is defined so that the Up Vector is parallel to the 5!W Q vertical side of the plane. The irradiance incident on the selected surface is AITV+=sN projected onto this plane. When the map is displayed, the up vector will point 4o7(cP toward the top of the screen.
