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”。 =#8 J9 XxV]U{i! 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： Ci=c"JdB Normal Vector o{m$b2BW The Normal Vector is a vector in 3D space that is used to orient the projection <"aPoGda plane for the irradiance map. The plane is defined to be perpendicular to the P !6r`d Normal Vector, and the irradiance incident on the selected surface is projected i7:j(W^I8 onto this plane. When the map is displayed, the normal vector is pointing toward 9
bGN5.5 you. naW}[y*y; Up Vector ( 8k3z` The Up Vector is a vector in 3D space that is used to orient the projection plane z&9vKF for the irradiance map. The plane is defined so that the Up Vector is parallel to the dorZ O2Uc vertical side of the plane. The irradiance incident on the selected surface is KYd2=P6 projected onto this plane. When the map is displayed, the up vector will point k QwBrb 4 toward the top of the screen.
