How to optimize 2Million poly interior scene?

Masters,

I'm trying to render an interior scene in about 2million poly count in MR and it's crashing really bad. Is 2M poly reasonable for a quite big interior scene?

I tried to bring down the poly and erased unnecessary objects and even reached 590,000 poly only and it's still crashing, some suspected custom objects were deleted as well, I couldn't rendered still, any tips on how to optimize poly in a scene.

I tried to xref all fixtures and furnitures already, should this help? di pa rin kasi pwede...

My last option will be MR proxy, but I'm trying to avoid it since I am hoping I can still make the scene work. My PC in the office is at reasonable specs, even at home, and I can usually render ok with them... itong scene lang po na ito ang nagkaproblem ako.

increase memory dynamic limit. or find "hotfix" for 3ds/vray to fix bugs and errors. i think. 3ds hotfix.usa..... keywords

wow, thanks dito sir... actually I'm really hoping to get an answer regarding debugging scripts or something...

pre MR proxy mo na....para dun naman talaga yung gamit nun. tapos kung pwede mo mapalitan yung mga items mo na high poly masyado katulad ng mga vases. at mga abubot pa......Good Luck!!! tabing guhit ba yan?

I don't think makaya ng system mo ang ganyang scene kaya nag crash. I have a scene before 8M polygon and im using Dual Xeon 3.4ghz 8 core 12GB ram "Windows 7 64bit ha hindi 32bit " it renders smoothly without proxy yun ha ..

daming factors kasi sir .. either ang mga shaders mo, lights (e.a. Blackbody), final gather mo baka sobrang taas which you don't need naman try to start sa draft then test ulit to low settings.. and make use of the technique like save Final Gather first with one material na simple muna tapos render mo using na save na final gather .. same as GI ..

pero most problems occur sa shaders .. hope naka help sir if not tweak natin

Thanks pre! eto testing 1-2-3 ulit ako with Hotfix!!! thanks ulit kay sir egypt! so far so good ang rendering... try ko na ata MR proxy.

hehe di pre, sa office to.. pero preparing na rin for tabing guhit for this week, may ibabato kasi sa kin yun contact, sana matuloy hehe

salamat pre!

sir ed, salamat po sa pagdaan, laking tulong niyo sir, maari nga po sa blackbody, babaan ko po yun final gather... yun sa FGmap po nakaugalian ko na din isave ito pati yun GImap... check ko na din po ang shaders.. update ko po kung ok na magrender.

sir egypt, sir ed, nainstall ko na po yun service pack ng max2010 and the hotfix 2010_2009.09.00 [pero crashed pa din po.. any tips how to use the hotfix or it's already working once installed? or it didn't really help me fix my scene errors? thanks po

I remember reading somewhere that when dealing with high number of polygons you should change your Raytrace Acceleration in the Renderer Tab of the Render Settings to BSP2. Try searching through Google I know one of them mental ray gurus preaching this. I haven't tried it out for myself though.
And optimize the maps you are using. Hope this helps.

hmmmm... another tip sa rendering sir??

Yan si sir edosayla- and daming tricks kaya nga ang dami ko din natutunan dyan kahit hindi ako naging estudyante ng mental ray classes niya. hehehe..

got it sir... I'll sure to try this. Maraming salamat sa pagshare ng inyong kaalaman MR master logikpixel!!!

hehe ako naman sir, I still consider myself as one of you 2 masters and MR teachers' student! kahit di po ako literal na nasa classroom niyo, for me CGP is our official school... glad to be your apprentice jedi masters!!!

same here mga masters....been an MR student here simula p lng...

anu nga kaya ung bagong tip na yun?? same as saving your IR Maps and light cache??

hintayin ko to mga sir!

sirs and masters, problem solved, had to delete a few objects behind my scene and deleted old maps and materials... was able to crunch it down to 1.5million poly with new materials.

sir logik, you mentioned about optimizing maps, is it the bitmap images of the textures (meaning limit the texture images I use) or the uvmap itself?

hehe cheers tayo dyan bro being MR students!!! yun saving FG and Photon map, go to your render setting, Indirect illumination tab, and at the bottom of this page you'll see the options on how to save these maps first in low rez before rendering in high rez... I'll get back to you on this, hanapin ko yun link bro.

ay oo nga pla nakalimutan thanks master logikpixel .. use BSP2 pla hehehe whew!!

markuz bro:


FINAL GATHER, PHOTON & GLOBAL ILLUMINATION FOR FAST RENDER
•Turn on Photon Map, use Read/Write File, then render
•Turn on Final Gather, use Read/Write File
•Lower samples to 1/64 - 1/64
•Render active time segment at every 10 frames
•Turn on final gather Read Only (FG Freeze)
•Increase samples to 1 - 16
•Turn on Save File for Render Output
•Render active time segment at every 1 frame

thanks sir for the support on this, definitely going to try this...

Very simple bro:


Sa Render Setup, Indirect Illumination, Final Gather map click Read/Write File. Generate Final Gather Map File Now. After your Render Frame Window stops calculating the FG map click on Read Only(FG Freeze).

Now everytime you render the specific scene that you have "FG Freeze(d)" it will render automatically without having to calculate FG.

One tip, when calculating FG use a small output (render) size BUT with the same(LOCKED)RATIO as your final render size and use a LOW FG Precision preset. After you saved your FG, you can increase the render size output and FG Precision for final render.
Please correct me if I am wrong but this is how I do it.

wow! salamat sir!

try ko to paguwe...!!! will post some new renders soon...

Masters, question na din po, I am suspecting it could be my multi sub object material, is it possible that this specific material is the one and only culprit causing the errors and crashing? kasi po nung hindi ko na ito ginamit nawala ang crash. I tend to use this mult-sub obj material in several objects and even 2 different sub material in one object and 2 assigned different poly... or is it ok to use it this way?

salamat masters sa pagsagot niyo po! very much appreciated.

got it sir logik!salamat!

@sir marcelinoiii, sensya na na-evade ata thread niyo,

more power CGP!

perfect sir logik, the best kayong mga masters!!! laki ng naitutulong niyo sa amin!!!

ok lang bro, we are all here to learn... no harm done always keep in mind, nandito lahat para matuto at tumulong, lalo ang mga masters and teachers natin... they are always happy hearing our queries
