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”。 ~ "<AYJlO ;au -NY 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： ?Y:>Ouv*z' Normal Vector |hsg= L X The Normal Vector is a vector in 3D space that is used to orient the projection HZp}<7NR(7 plane for the irradiance map. The plane is defined to be perpendicular to the b?6-lYE>L Normal Vector, and the irradiance incident on the selected surface is projected I]HrtI onto this plane. When the map is displayed, the normal vector is pointing toward !d@q T. you. N5>ioJj Up Vector X.u&4 SH The Up Vector is a vector in 3D space that is used to orient the projection plane Te%2(w,B for the irradiance map. The plane is defined so that the Up Vector is parallel to the M2U F3xD vertical side of the plane. The irradiance incident on the selected surface is !f
7CN< projected onto this plane. When the map is displayed, the up vector will point 9M3XHj toward the top of the screen.
