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”。 ?Ee?Ol?i2 .2Q`. o) 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： RF6(n8["MW Normal Vector (d# ? \ The Normal Vector is a vector in 3D space that is used to orient the projection B'yN &3 plane for the irradiance map. The plane is defined to be perpendicular to the J4`08, Normal Vector, and the irradiance incident on the selected surface is projected g'pE z onto this plane. When the map is displayed, the normal vector is pointing toward @sfV hWG you. bXJ, L$q Up Vector E'MMhl o The Up Vector is a vector in 3D space that is used to orient the projection plane 71 K6] ~< for the irradiance map. The plane is defined so that the Up Vector is parallel to the %*|XN*i XC vertical side of the plane. The irradiance incident on the selected surface is ucoBeNsHx projected onto this plane. When the map is displayed, the up vector will point U?#6I- toward the top of the screen.
