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”。 RD=V`l{Z eTay/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： R 5%CK_ Normal Vector i3Bpim. The Normal Vector is a vector in 3D space that is used to orient the projection `9+R]C]z8 plane for the irradiance map. The plane is defined to be perpendicular to the *|<~IQg Normal Vector, and the irradiance incident on the selected surface is projected 'b z&m( ! onto this plane. When the map is displayed, the normal vector is pointing toward G2 ? # MO you. `j 9\]50Z> Up Vector -aS@y. z The Up Vector is a vector in 3D space that is used to orient the projection plane @"1Z;.S8V for the irradiance map. The plane is defined so that the Up Vector is parallel to the u' Q82l&Y vertical side of the plane. The irradiance incident on the selected surface is ,\c V,$ projected onto this plane. When the map is displayed, the up vector will point t [|t 0y8 toward the top of the screen.
