fast rendering at the beginning too slow after few renders

Good day po sa lahat ng mga master, I need your help kasi sa umpisa mabilis magrender ang PC ko pero after several views rendered bumabagal siya. at first I was rendering around 20 mins per frame but after rendering several views i was rendering ridiculously 1 hour just less than half of every frame in region rendering.

scene status: autocad linked architectural model + max models for accessories = 2 million poly counts




this is my set up:

1400 x 2000 pixel
AA: adoptive DMC, / catmull rom / min 1, max 4
max tree depth:80
Dynamic memory limit: 8000 mb
default geometry: dynamic

All GIs are saved before the final render.

this is my PC specs:

12 GB ram
NVDIA graphic card
I7 processor

nakakalungkot isipin na Ive got a good rig but low perfomance.
my boss was not happy.

mga masters could you please help me find a solution to this problem.

that is normal cause of your furniture sir i hope it will help

actually yung furniture ko nanjan na when i started rendering the first view pero pagdating jan mabagal na..hindi ko malaman kung bakit every time may bagong project ok naman pero pagkatapos ng ilang render bumabagal na kahit bumalik ako sa unang view...

check mo mga materials mo, make sure na atleast 1mb (max) lang ang isa...make sure na iisang folder lahat ng material at xref...check mo rin mga reflections at shadows mo...avoid mo na rin ang mga bump kung malayo rin lang sa camera...

Always restart your max before you render another view.

thank you master. i will check my scene. regarding po dun sa problem na mabilis sa yung mga unang renders but after few views has been rendered saka sya bumabagal ng more than twice its render speed, what do you think is the cause? hindi lang po sa project na to naencounter ko yung ganitong problema kundi sa lahat. that is why nagpost po ako because i was sure na yun nga yung problema kasi common sya sa bawat projects...

thank you sir i would consider to try that option...

One more thing, I usually avoid linking cadd drawings in max. In my experience, nagpapabagal sya at nagpapabigat ng scene...

kung common yan sa mga pag rerender mo, heto yung mga nakikita kong problem:

-follow what sir torvics said
-check your max & vray settings
-check mo rin yung mga model na ginagamit mo & check all your parameters (normally im using poly)
-check all your lights na maraming shadow

Try mo irender yung sinasabi mong view separately. If it will render fast, then there is a big problem. Pero kung slow pa din, then meron something sa scene na heavy on the rendering, it could be a reflective material or a high poly object.

i think this is the culprit.. in my experience nag switch ako from 3ds max 2009 to 2010 para updated pero here's the thing.. just like you've said super bagal nya magrender kahit simple settings even my friend is having problems with rendering that is eating a lot of time doing a low settings render, then i tried to switch back to 3ds max 2009 and found the solution.. so until now i'm still using 3ds max 2009, pero try mo lang naman if ever baka makatulong.

But he did not mention that he switched from max2009 to max2010.

In your case dude, you can still use max2010, provided you merge your old file instead of opening it to max2010.
I had the same experience before because I upgraded from max9 to max2010.
Sobrang bagal talaga. But that was solved.

sir ngtry po akong irender yung 1st view naging 3 hours yung estimated time nya dati 20 - 30 mins lang. without adding anything into my scene exept camera.

Mag trouble shoot ka dude.

1. override mo yung materials, say white diffuse only.
then render mo, pag bumilis meaning sa materials ang problema mo
pero pag mabagal pa rin....
2. try mo uncheck yung lights mo sa global switches.
pag bumilis meaning sa lighting ang problema...
3. or you may also merge the file to a new one....
do this batch by batch, render each time you merge. minsan may isa
lang dyan na object na gumagawa ng problema eh...

try mo lang dude....

what i want to say is that parang may problem ang max 2010, kasi nag compare na ako ng low render settings sa 2009 at 2010 nung time na nadiscover ko ba't super tagal magrender ang 2010 at mas mabilis magrender ang 2009 kesa 2010, yung low settings sa max 2009 will take 4 mins, samantalang sa 2010 mga 10-15 mins so nakapagtataka, sa friend ko na ang tagal mag render halos 3 oras di pa tapos kaya nag switch sya sa old scanline just to make it on the deadline, she's using default render settings sa vray dahil di pa nya kabisado until i discovered na she's using a core i3 laptop eh samantalang ako core2duo lang na dapat mas mabilis sya compared sa akin so nung nagcompare ako ng low render settings sa 2009 at 2010 i recommended her to switch to 2009 after nung nadiscover ko na mabagal sa 2010 at ayun problem solved, at dahil sa nangyari im skipping 2010 to 2011 pero version lock muna ako sa 2009 anyway suggestion ko lang naman baka makatulong if ever.. im using Vray 1.5 SP5.

Dude andy, try mo lang yung suggestion ko sayo. Don't open the file just merge it. See if it is still slow. Mabagal talaga pag in-open mo lang yung old file mo sa max2010.

But if you say 2009 is better than 2010, I wouldn't mind, I have no problem with that. Case to case basis na rin siguro. But I don't get the logic that lower version is better than the higher one(rendering wise). Sorry OT na. Gusto ko lang banggitin, baka kasi ma-encounter din ng iba....

Pirated Max2010+vray is buggy & problematic. The Registered official releases aren't.

IMHO. I dont think its cause by software version. Most probably is the scene or the settings. With your specs its fast enough to handle your scene. The fastest way to solve your problem is upload some screenshots here of your settings or the file itself. so that we can help disect to see the cause of the problems.

Also try this if it helps:

agree to this...



kung okey lang syo bro send mo sa akin yung file tignan ko kung anong problem. i been using 2010 for a year wala naman akong na encounter na problem like what youve encountered. meron nga sigurong bug yung 2010. norman_caguiat@yahoo.com

i tried merging na rin pero ganon talaga ang tagal ng test render settings ko sa max 2010, yah actually higher version is really good para updated pero in my case sa vray yun nga naging problematic sya kaya nag switch back ako sa 2009.. i'll be switching to 3ds Max 2011 soon..

sir arkirein kapag mabagal ang rendering go to customize>>preferences>>go to rendering icheck mo yung multi-threading kailangan na ka on iyon kasi same kayo ng problema ng kasama ko kasi hindi nakacheck yung multi-thread halos 2 buckets lang ang lumalabas na nagrerender mabagal ang rendering hope it helps
