help~ about mental ray again~

[Solution]

Hi~ I have problem with mental ray again~
In the scene, I have put a spot light outside the windows and wanna make a light-shadow on the floor and with diffuse in the room. But the outcome image seems that only diffuse exist, the light shadow of windows doesn't appear, can anyone help me to test my scene, fix it and then post me how to adjust the setting in order to get back the light shadow??

hi aries~
last time u have help me to test render a scene with the word "TRINITY" inside, do u remember? um... you report your render time of that scene is about 14min, I want to know have u edit the global setting of that scene while u were redering it? because i now get a new pc with p4 2.53ghz and 1G ram, render that scene (leave all setting without change) still need over 30 min.............

造成rendering時間慢有很多因數、
以MAYA的Mental ray來說
有很大可能是FG的ray數設定得太大（內定1000）、
試一下用400以下。

其實FG有使用及無使用時rendering時間上已經有很大的出入。
如果FG設定得好rendering應會快很多、
其他的只有不斷test、test＆test...

so, last time u help me render trinity.mb, have u adjust any setting of that scene to render? that scene default is 1000 final-gather rays with radius 0. do u have any impression?

上次是用本身的data作render、
並沒有作任何改動。
