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”。 w3;{z ,,T . ' >d7 另外，分析图的颜色和项目也可以在Irradiance/Illuminance Options中设置。
K r<UPr Analysis----》Raytrace Options修改Radiometric的方式就可以了。

站长说的很对，补充一下： /1D.Ud^ Normal Vector !N_eZPU.v The Normal Vector is a vector in 3D space that is used to orient the projection =;F7h
@: plane for the irradiance map. The plane is defined to be perpendicular to the c4r9k-w0E Normal Vector, and the irradiance incident on the selected surface is projected 9]l yV onto this plane. When the map is displayed, the normal vector is pointing toward ^QG<_Dm] you. .JJ50p Up Vector f! )yE`4- The Up Vector is a vector in 3D space that is used to orient the projection plane ]m7x&N2 for the irradiance map. The plane is defined so that the Up Vector is parallel to the ie>mOsz vertical side of the plane. The irradiance incident on the selected surface is F- M)6&T projected onto this plane. When the map is displayed, the up vector will point 9'e<{mlM toward the top of the screen.
