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”。 Xaw ~Hh) zCdc wTe 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： $Ai zKiV Normal Vector [FZq'E"87 The Normal Vector is a vector in 3D space that is used to orient the projection -Jf}3$Ra plane for the irradiance map. The plane is defined to be perpendicular to the yp[,WZt Normal Vector, and the irradiance incident on the selected surface is projected ^#XQ2UN onto this plane. When the map is displayed, the normal vector is pointing toward FKPR;H8> you. hV +=hX<h Up Vector !L@<?0x LW The Up Vector is a vector in 3D space that is used to orient the projection plane eL<jA9cJ9 for the irradiance map. The plane is defined so that the Up Vector is parallel to the ^ FM vertical side of the plane. The irradiance incident on the selected surface is vOLa.%X]h projected onto this plane. When the map is displayed, the up vector will point kZ PL$ \/A toward the top of the screen.
