vray setting problem.... (UPDATED with OUTPUT)

mga masters... i just want to share my settings po... im really pissed of waiting so long for my renders... ang tagal po talga.. it seems that there is something wrong sa setting ko... to all generous heart there... patulong nman po sa aking problema...

my render time is more or less playing at 4hrs and more... at 1800x1350 resolution...

sample for this render...














some materials...







my materials subdivs usually plays at 8(min) - 15-25(max)
ordinary paintings have 8subdivs only.. i just increase the subdivs pag i see unwanted glossiness/noise sa render output.

for my interior lighting i use vraylights and photometric lights for this particular scene. for my sun, i used the target direct light of max...
for my camera i used the target direct camera.. tweaked some lens settings and applied CC.



BTW : the setting is for my final render output... good output. pero matagal lang talga

my work machine...

CORE2QUAD Q9400 @2.66 ghz - processor
4gb team elite 800 RAM
500GB HDD 32 cache
PALIT RADEON HD 4850 DDR3 Sonic 512MB - vcard
ASUS P5K-E mobo
800 watts ZUMAX powersupply...

with all the fans and other accesories.

i guess, this is a great set-up already namn... huhuhu... been using this workstation for quite a bit, mga 2mos na. i was just observing the performance. actually this workstation is my personal, i tried rendering the same file sa office, times 2 pa ung render time. ang tagal po talga. so siguro sa settings ko talga ung problema.

HEEEELLLLLPPPPPPP....



.

reasonable enough naman. maganda naman ang output.

what you can do is gawin mong very low ang ir settings and 100 ang lightcache. compare mo yung quality versus rendertime.

as in.. ganun ba talga master boks? hmmm.. if i lower the ir and gawing 100 ung subdivs sa LC, parang im using my test render settings... which only took mga 5-15mins of rendering... pero d ganun ung output po.

what im up to is kahit mga 2hrs na rendering time, with more or less the same output - ok na po sa akin. hehehe.. pero if ganun talga real time - render time nya.... hai....

nwei.. tnx master boks sa pagbisita and sa advice...

Sir vamp lestat, try mong i-Medium lang yung Irradiance Map mo then balik ka sa CUSTOM then palitan mo yung MAX rate ng -1 and Min rate -1, HSPH 50 and Interp sample 20

either sa materials bro or dahil nakaSP2 ka. di ko actually sure. pro sa settings ko, ok naman ang labas. lugi na kasi ako nyan pag more than an hour na render na.

Here are my points:

1. I notice that you used VrayLanczosFilter in your AA, haven't tried that one but I dunno if that matters with the speed. Try the Catmul and see if there's a difference.

2. IR Map set to LOW, yeah I tried it before I couldn't see a big difference between MED and HIGH. Basic Para: 60,40.

3. Light Cache Subd: 500 only.

4. THE REST SET TO DEFAULT.


Have a test...I hope it satisfies you...

hmmm... alin ung sp2? ung vray po? nwei, my os is xp 32 bit po.. sp2 din... mmm... can u post po ur settings? just to compare master boks... or pa tweak neto na aun sau ok po ang labas. tnx... wil appreciate it a lot.. if ever...

master kurdaps... kk. il try this setting. il update po... the AA.. i guess. alang difference.. i tried catmul pero there are some sharp edges na ayaw ko... i prefer doing it sa ps...

alam ko na, glossy effects sa global switches. ito pala setup ko, saka boks nalang please. ayaw ko ng master.

master kurdaps settings....



@kurdaps

tnx po master kurdaps... i guess ok na ito for me... less render time na di namn pala maxado kita ung difference. i compared it sa hi-res... ung level of detail lang sa orig setting ko and sa tweaked setting me difference... like for example sa fabric di maxado fine, sa lighting medyo sabog pa, sa edges a bit blurry... pero ok na ok na xa... hehehe... i guess il have to stick with this. kakapagod talaga po mag-antay....

@bokkins

master bokkins... ooppsss... sorry po.. geh nlng po, hayaan nyo na ako. humahanga lang at gumagalang.. at talga namn isa kau sa mga masters na hinahangaan ko.
nwei, havent tried unchecking the glossy effects yet.. later after work, il try it... if ok pa din xa, i would combine the settings that for me ok na.... tnx po

@3DZONE

sir 3DZONE... mmm... havent tried your setting po... medyo late na kasi kanina... nakatulog na nga po ako. nwei, il get to it din later... pero i guess the medium IR would take more time. nwei, tnx2x uli master...

O.T.
i really want to meet you guys and thank you personally. napaka generous nyo po at lahat ng CGP members. sana me grand EB.. thank you ng marami... especially you guys here.. kurdaps, bokkins and 3DZONE... mga masters salamat talaga...

just to compare at closer view...

orig settings output



tweaked settings output

[quote="kurdaps!"]Here are my points:

No problem i think if you use vray lancoz filter bro!! Isaw the problem in your settings.. My suggestion are:

1. Under Apadtive Dmc image sampler
- change the value insted 1-4, make it 2-5..uncheck use DMC sampler thrshold to speed rendering...

2. in IR MAP rollout
- try to use low settings but change the min& max value to ( -4, -1 ).. also change the hmspheric subv to 70, & inter sample to 30.. No need very high for this becoz i will blurred the G.I.

3. In LC rollout
- 1200 value in calculation parameter is high i think that affect to rendering time.. 600- 800 is enough. change the number of passes to 4 only..
- check the use light cache for glossy ray in reconstruction param. becoz you have a lot reflection & glossy effect in your scene.. i'm sure it will boost your rendering time..

4. The biggest problem in your settings is in VRAY DMC SAMPLER
- change the adaptive amount to 1 if you're not using HDRI in your scene.. This will help to reduce rendering time.. Also the noise threshold to .01 but you need to increase the color threshold to .005 under adaptive DMC image sampler to reduce noise but still fast rendering time..
- change minimun sample to 10. your value 16 is very high bro.
- The last thing i want you to know & to change is global subdivision value.. Why you are using 3 value? ( If your vray material is high subv like 16,20 or 25. No need to high the global subvdivision but if your vray materials is 8 in subd value. Increase your global subd to value like 2.. It means double of subvdivsion of your materials globally..That why your rendering time is very high.. That is the reason..

I hope this will help you.. This all settings are base on my experience and researching.. Try to render again bro.. I'm very sure that your rendering time is maybe less than 30 mins..Thanks!!

master butz, thnx po for the reply... i ran a test render for the tweaked settings you gave... i followed them all in this particular render

this is also in 1800x1350 res



unfortunately, there are some issues regarding the render that concerns me... first - there are details that are lost in the render... it can be seen in the clock and the curtain... hmmm... they bought have transparency. i guess this is because of the "use light cache for glossy ray"... dunno really... next are the unwanted noise and blotches... though the best part of it is the fast render... it only tooks 31+mins ( di po kinaya ung less than 30mins ) .... nwei, amazing lang din po... coz now i have more option... i can play with these settings until it would satisfy me, something that is not bad, but would be considered good... importante po kasi, lalo pag rush projects.. maraming salamat po uli sa inyo master butz...

wow! parang tutorial section narin to ah. galing talaga.

pareng vamp i think ok lng namn ung render time since you are using high settings plus ung mga subdivisions mo. and u are usign materials.ung curtains mo dn i think mdyo matagal iredner yan. and ung resolution mo kac 1800x1350 tama lng yan bro. just imagine nlng ung time pa ng mga pentium 4 hahaha! wla pa core2dou and quadcore.ilang days kya matapos ang ganyang klaseng scene???hehehe!

Ya know - and I remember mentioning this here a couple of times -

If you have lots of glossies (DOF, glossy ref and refracs, MBs) - you'd need to use Adaptive DMCs, if none at all then use Adaptive subdivision.

One thing I noticed in the settings above - is that you have set a very high global subdiv thinking you could compensate for the low glossy subdivs in the local mats. This and that is very wrong in your typical vertex opinion.

Doing the above will automatically set vray to triply inverse its efforts in sampling your scene - and that include areas where it does not need to.

For speed, my workflow is as follows: I set my glossy ref's subdivs to something more appropriate - a default of 8 will bring out noise no matter what you do. Anything below .6 equates to something around 32 subdivs. Anything above will place in the minimum of 16 to 24.

So what's the purpose of the globals subdivs you'd ask. Use it as a final arse -senal. So if you are able to fine tune the render at the default global value - turning the global dial a few more than the regular value will assure you that the renders or the flickers or the samples will be a lot better that before you turned it on.

And oh - one more thing - noise of course will be more pronounced and difficult to smoothen out if you use sharpening filters - so use them with caution.

I'd like to add - vray light shadows subdivision values also play an important role in the general samplings area if you do not tune it properly.

If you see noise in your shadows - don't be afraid to up the subdivisions per light - doing so will ease the burdens on your global samplers and you'll notice a slight increase in your renders.

nice bro vertex!!you're very good!!

Consider SPEED v.s QUALITY. but your setting is high enough. Probably adjusting some of your subdivs might help.

tnx sir v... just visited this again... its clear to me now... mmm.... the thing is i thought that increasing the global subdivs would decrease the noisiness of my scene... have no clue it would affect all the subdivisions that i put.... waaaaa...

and one more thing, i read a tutorial that to eliminate the noisiness you must increase the subdivs of lights and if you have so many lights, it would be so hassle to increase those lights one by one especially if its not instanced. so the solution was to increase the global subdivs... totally bad tutorial. just teaching begginers to be lazy. hehehe... i was an innocent victim though... tnx guys that you're here...

also the thing about the more pronounced noise.. i noticed that too. dint expect its because of the global subdivs.. tnx for mentioning it.

thanks for sharing your Vray setting....this will be useful!

You are welcome. There is a vraylight lister script lying around somewhere. You could probably use that to increase the light shadow subdivs.

Yes i sencond emo to sir V the vray light lister very important menu for lighting and rendering, all of the lights in the scene are in the menu and you can alter the intensity subdivisions and so on....

vraylightscript posting here soon.
