Wip Interior : Noise problem

[KruL]

Hi vray gurus !

I'd need a little hand on an Interior viz for an industrial environment.
I've done all I know but still...have a little problem with noise as far as I can see...

Here's the image



Here's the setting :


any tips welcome

Change your anti aliasing over to adaptvie qmc for speed since you are using so many glossy effects. You can either up the samples on your glossy materials to something around 24 and in the qmc sampler rollout change your noise threshold down to 0.002 and gradually bring the adaptive amount down - try 0.8 and go lower if needed.

thanks for your speedy reply

trying it now ! Just one thing : what values would you recommend for min and max subdivs for adaptive QMC ? Do I keep default values or do I use vlado's universal setting (1 to 100) ?

thanks for your time

well i think it looks great except for the noise...and maybe it could use some more light bouncing until that ceiling
...
as a general settings i would try the following:
adapt qmc 1 - 4

adapt amount 0.85
noise treshold 0.002
min samples 10
global subd mult 4

i sure hope u fix it cause its lookin great so far!

The standard one so far has been 1, 4 since 4 times oversampling is good enough for nearly everything. In your image the only places you're getting problems is in the glossies which is down to the material sampling and qmc settings - Vlados settings would probably work better if you knew you were using them from the very start since they will affect how many subdivs you put into any quality setting in vray.

Maybe look at using his settings on the next project you start instead?

thanks for your help mates...
working on it now, it seems that the noise has vanished as rendertime increases more and more...
I'll post results as soon as I get some

salut Krull,
Welcome in the world of QMC AA.... and sampler.
let the default value to yor QMC AA, and play just with the noise threshold in the QMC sampler, after some "bon vieux réglages" you should have better rendertimes.


PS: your IES light are to strong IMO.

hep priad ^_^ merci pour les conseils j'essaye

6 hours later and still half the image to go... (1600x1200px)
cancel it and continue tweaking

[KruL]

here we go



5 hours for the rendertime in fullres (1600x1200) on my turbojet bixeon ... I'll post other pics.
thanks for your help

Quite satisfied with quality. Thanks for the advices ^_^. Comments and crits welcome.

everything is looking great it just feels wrong the light emmited by those large fixtures to be burning the floor more than the direct sunlight...

great images krul - all 5 hour render times??

the spots look great, where did you get the ies file for those (i'm assuming photometric?)

thanks

ene.xis : you're right, the vraylight's multiplier is too high.

shelsby : yep all about 5 hours rendertime, as .vrimg 1600x1200px ; as the ies file, I use it for such a long time that I can't figure out where I got it

thanks for your comments
