Mental Ray Render Speed Test (Updated with Trial Animation)

First topic message reminder :

Sirs and Masters of MR,

I purposely posted here for a discussion regarding MR render speed.

Lately I rendered this Image 1 below in a low setting at 1200px max size. The render time took more than 8 hours.
Image 1


I couldn't understand why until tonight and made a render of Image 2, the same size at 1200px max in only 50min.
Image 2


If you guys can observe, Image 2 has no physical lights on. No portal light, no free light etc... I only have an MR sun and controlled brightness with MR Photographic exposure. But the output is quite ok... My question to the masters, did I do it right?

Conclusion:
1. In Image 1, I have too many lights and my intensity/multiplier si reaching from 10,000-100,000 which I think is the cause of slow rendering. So we avoid jacking up or lighting our scene this high, and we adjust brightness on exposure instead.

2. In Image 2, due to no-light at all, my exposure turned out to be:
Shutter Speed: 40
Aperture (f-stop): 5
Film Speed (ISO): 100
These setting is beyond normal or far from default which are: 512, 8, 100 respectively.

3. Anyway, my only point here and the mistake I've been doing, don't use too many lights and don't jack it up too high... my bad

I hope this experiment helps the newbie MR users like me.

Masters and teacher's suggestion and recommendation would be greatly appreciated!

Best Regards to all!!!

Please check out my first ever attemp on interior animation with max2010 and MR. PLease forgive me with the compressed version as it is my first time to post on vimeo. I'll try to upload higher quality later. Also, pasensyahan niyo na po, this animation is quite short and intended only for MR render speed test. Low MR setting of FG only in total 16 hours of 240 frames at 30fps, approximately took 5 min per frame. I am really hoping for tips and suggestions from the masters.

GI and FG are best used TOGETHER in interior scenes. It can give accurate lighting solutions to any scene. I have an example in my site of what I am talking about. Also you can check http://www.i3dtutorials.com/tutorial/73_global-illumination-and-final-gather-in-mental-ray-for-3ds-max-2010 for further explanations.
Anyway, for exteriors you can get away with just Final Gather. Then you can add bounces, a maximum value of 2 is more than enough. Learning the mr photographic exposure settings would help a lot.

Good scene test. I suggest adding Ambient Occlusion sa materials to add more depth and realism.
Keep it up.

Agring-agree ako dyan sir logik mostly kapag sinag lang ng MrSun at MrSkyPortal sa butas ng bintana ang source ng ilaw dyan gamit na gamit ang GI alternative lang naman para dun sa mga mababang specs na computer to turn off yung GI lalo sa studio lighting dahil direct naman yung liwanag papunta sa object sometimes hindi physically accurate pero sa output naman makikita yan as i have shown sa dalawang imahe sa taas halos pareho lang din with & without GI but the lesser time yung isa.
Thanks sa link sir laking tulong to sa mga mental ray user GODbless CGP rocks!

Wow ang gagaling nyo na sa mentalray a .. post ko din yung mga speed findings ko later for now just want to say hi at thanks for the share hope marami ang nagbabasa sa mga tips in tricks sa mentalray don't worry marami tayong secrets sa mentalray ilalabas natin dito hintay lng pasensya medyo wala na masyado na post busy kasi sa work at sa pagtuturo .. meron pla ako na prepare na tutorial sa exterior gawa lng ako ng thread para sa tutorial na yun .. thanks sa support sa CGP..

dont worry... nagbabasa ako.. galing mo nga eh...
