Good result What's the AA, and DMC sampler?

[LarsSonparsson]

Sorry, don't have time to explain settings more. Have to run.
You have my version of the scene in your inbox.

Cheers,

[cecofuli]

Ok, don't worry.
I would like also to understand the possibility to have good time with BF+LC + sub-pixel off.
RT, CPU and GPU version and PPT look like not a good solution for an interior scene.
Anyway, 2 hour for 1024px, for my opinion. it's a lot of time with new Intel CPU.

[Morbid Angel]

Yeah this is pretty tough. No matter what settings you input into this scene...render time does not look good, or you have noise.

[LarsSonparsson]

Yep. 2 hours for that resolution is no go. Bf+lc wasnt even an option. But I dont think it's the gi solution taking time in this scene. It's mostly glossy reflections and refractions combined with dof that is making it so hard to calculate. And when putting those to this overbright environment... hmm.
Have you tried to render underexposuring it and tuning the brightness back in post?

[Dariusz Makowski (Dadal)]

Heya

Any chance to get this scene for Maya?

I'd like to give it a go

[cecofuli]

I can send you the max file. We don't use Maya

yes, I think the same. VRay is very slow with glossy reflection when sub-pixel is off. Vlado wrote about the new VRay:
From Vlado. "Since we don't have adaptive multibounce sampling yet, you will have to find other ways to remove the sources of the noise".
But... in every interior scene, usually, you have to work with glossy walls, floor and ceiling.
I don't want to underexposuring it and tuning the brightness back in post. It's not a correct way to work.

Have you tried SolidRocks?

Solid Rocks i2600

30 minutes 15 seconds

[cecofuli]

wxyz, thanks, but the rendering looks very different. Why?
What's your color mapping/camera parameters? Did you change something?
Also, on the right side, inside the dark furniture, you can see some splotches.

[wxyz]

I guess I saved as an exr and compensated by hand out of habit, will try again when my other renderings are done.

[raymarcher]

A bit beside the purpose of this thread but a tip:

What I sometimes do is noise reduction, if carefully executed you can get away with it (carefully=per channel).

[cecofuli]

Thanks raymarcher, we do the same

[Morbid Angel]

Im curious do you DR your renders? if so how many machines and what is the actual render time you get for a 3k frame?

[cecofuli]

Morbid, are you talking with me? Corona doesn't support DR in the actual Alpha4.

[Morbid Angel]

Morbid, are you talking with me? Corona doesn't support DR in the actual Alpha4.

No I was talking about vray. When you go to render your final image do you DR it? I mean this has been common practice for a long time. Just wondering what your standards are.
