我在3D里建完模了,灯光材质什么的都弄好了,然后就按Rendering----Advanced Lighting----Radiosity按钮,结果出现下面的对话框...是怎么回事....现在还没懂呢斑竹知道么.....

那个偶试了好几次还是贴不上图,奇怪.....所以偶就直接打上对话框的字了，帮忙看看．．．以下就是．．
Radiosity....
  ?       You are assigning the Radiosity plugin
            It is recommended that you use a Camera Exposure Control with it.
            Would you like to chang this now?
