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”。 H~+D2A R |h9 ilc 另外，分析图的颜色和项目也可以在Irradiance/Illuminance Options中设置。
n K1XJp Analysis----》Raytrace Options修改Radiometric的方式就可以了。

站长说的很对，补充一下： cC1nC76[ Normal Vector pq+Gsu1^ The Normal Vector is a vector in 3D space that is used to orient the projection P~iu|j plane for the irradiance map. The plane is defined to be perpendicular to the lh3%2 Dq$ Normal Vector, and the irradiance incident on the selected surface is projected \TkBV?W onto this plane. When the map is displayed, the normal vector is pointing toward wx
