Noisey Lounge

How can I improve the detail and reduce the noise, I already used quite high settings, but it seems to be fuzzy?

Hard to see with the jpeg artifacts.
What Gi methods are you using, which types of lights?

[marshalartist]

I have used an infinite light as a physical sun and sky and added light portals in each window to give more ambient light. For the GI I increased the DMC to 16 on min Sam, irradiance min/max -3, 0. HS 70 IS 30 and the Light Cache Sub 2000. I have Adaptive subdivision on AA and colour mapping set to exponential with sub pixal mapping.

Here is a bigger version

Alright, these come from the light portals. Increase the subdivision samples in the area light tab.
You can also juggle with AA a little bit, but I strongly advise against changing the values of the DMC sampler, unless you know what you are doing, because this will change subdivision on the whole scene (for blurry effects and GIs as well), and could slow your render down quite a bit.

I think your GI settings are a bit overkill for this kind of scene.

[marshalartist]

Thanks Fluffy, I will experiment with what you have suggested.

marshalartist,

Hope you are well,

just wanna ask you, the image in the back- is the sun not coming from the opposite side as in the room?

Well spotted yes, I need to rework the photos and dress the garden up, it is a bit of a mess. I should have taken the photos at the right time of day but did not get a chance.

i personally never use light portals, as vray is very fast without too and i feel has a better image then.

cheers

Well, the whole point of light portals is to use lower GI settings, otherwise it's overkill.

The light portal is used to direct GIs through an opening, so that GI calculation are not spread throughout the scene, but solely on these portals. Speeds GI calculations quite a bit, and refines the GIs coming from these (hence the sharp shadows - which are not area shadows but GI, really).

If you need more light coming from your openings, then increase the light source strength, don't add some.

[marshalartist]

The light Portals are definately improving the image giving a better spread of light especially around the door well and facing walls. The downside is it is taking twice as long to render, increasing the Portal subdivision is getting rid of the noise but taking much longer. I reduced the GI settings a lot but noticed some patchyness coming in so went for a comprimise. I think I have found some good settings now. I will post with and without the portals so you can see the difference, thanks,

Ok here are the two version, with portals first then without.

I personally prefer the one without then (second image). I like the subtle color on the wall and the beach wood is great. IMHO.

[glass.use]

the second is better imo, nice update :D

[marshalartist]

thanks glass.use I prefer the first one myself but it takes four times longer to render!

[Fluffy]

Looks like your GI settings are not high enough on the second one, to compensate for the missing light portals.
Increase the physical sky (or whatever light source you used) intensity as well.
As for the color, a little white balance fiddling would bring it closer to the pink hue you got on the first render.

[marshalartist]

Thanks Fluffy I will try again.

[marshalartist]

Yes I am pleased with this one, thanks. This took 16 mins at twice the resolution shown here :D

good good zero zero good zero zero good


why you don`t use white balance in phys camera?

[glass.use]

and exponential in the bedroom. :wink:

I did use the white balance and exponential I have tweaked the settings and upped the dark multiplier a lot.

nice testing Pete :)

in general,for archi rendering, i'd advise against window light portals and work your light solutions around to suit without them. they're not a natural phenomenon and a render will ultimately look more realistic without them

[marshalartist]

Hi Steve,
there are no portals now, after taking advice I ditched them and just used physical sun and sky. Steve send me an email with your contact number on again, I lost a lot of emails over the weekend.

[STRAT]

done :)
