HELP again! mental ray!

[Solution]

I donno why every time I render the scene "trinity.mb" which given in the mentalray 3.0 pirate CD can successfully render without problem(the maya output windows will jump out and showing "10%photo map, 11%photob map.....), but the scene that I create and render with mental ray will just show "lens shader.....it must not move the origin or direction of ray" and no any othe rmessage come out, and the most important, the render ALWAYS fail, the probability should be, render 5 times then the rederer will down and need re-start maya. do anyone got this problem before and know how to solve??
(P.S: I've re-install MAYA 4.02 and mental ray (include mayatomr) for many times, so I can sure that must be somethings wrong rather than the software is corrupted)

可以說一下在Render前MentalrayGlobals的設定嗎？
例如RenderQuality、GIPhoton數量、FinalGatherRay數量等、
還有你PC的機能。

my computer is a low-end model, just a p2-400 with 512mb ram model, but i don't mind run it over night to render the scene~
I've put the given "trinity.mb" and my simple scene "radioroom.mb" at the following website, please right-click save-as download and click render to see you can render my scene or not, and will the output window show "10% photon map ..." while render my scene or not?? ( i don't have such message while render my scene but the trinity.mb does have these message)
Please help me~

看來是你PC或software的問題...

My PC:Dual P3 1G, 1GRAM
Software:Maya4.0.2, Mentalray 3.0.5

thanks aries for help test render my scene~
but I want to know, while you render my scene "radioroom.mb" do the "output window" showing "10 % photon map..11%..12%.." such message?? because I can't get such message while render radioroom.mb but I can get such message while render trinity.mb~??

[aries@CAVIS]

It did not see message in output window on rendering.

[Solution]

oh~ if I render the scene and interrupt them in the process for several time, then the renderer seems easily corrupt and need restart the maya to render the scene again, how to prevent the renderer to corrupt?
and also, do u know why the trinity scene will have "% of photon map" message output but my scene don't have??

[aries@CAVIS]

Open MentalrayGlobals>Translation>
choose Export Verbosity type to Progress Messages
than you can see the message in Output Window on Rendering.

[Solution]

oh~ progress messsage~
while I use the same global setting in my scene "radioroom.mb" as "trinity.mb" (global illum accuracy - 64, global illum radius = 0, final gather rays - 1000, min/max radius = 0), the trinity scene just use 38min but my radioroom (as u can see, very few and simple objects inside) used 70min, why??

[aries@CAVIS]

我也不太清楚、
一般做成Render時間過長的主要原因是scene太復雜
及final gather rays太多而引至。
要多測試才能理解。
i just can said “keep trying”

[Solution]

thanks very much aries~ you help me so much about this topic~~
i will keep trying and testing~
