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”。 ur

站长说的很对，补充一下： $lhC{&tBV Normal Vector -=.V
' The Normal Vector is a vector in 3D space that is used to orient the projection ]v#r4Ert plane for the irradiance map. The plane is defined to be perpendicular to the 1heS*Fwn' Normal Vector, and the irradiance incident on the selected surface is projected w[6J
` onto this plane. When the map is displayed, the normal vector is pointing toward l2; CQ7 you. RT>{*E<I Up Vector V13 8d?Mm The Up Vector is a vector in 3D space that is used to orient the projection plane ~EK'&Y"1 for the irradiance map. The plane is defined so that the Up Vector is parallel to the u*qV[y5Bl vertical side of the plane. The irradiance incident on the selected surface is 7Sz?S_N/j projected onto this plane. When the map is displayed, the up vector will point *6 _ tQ9G toward the top of the screen.
