Solar irradiance decreases towards the poles. 太阳辐照率向两极递减。
Below there are Irradiance map and Antialiasing settings. （下面示光子贴图和抗锯齿的设置。）
Irradiance map + Light cache: the mostly used GI combination. 发光贴图+灯光缓存：GI的最常见的组合。
However, Irradiance Particles are compatible with caustic photons. 然而，辐射粒子与焦散光子不冲突。
