kitchen, noise problems

[Sdados]

ok... done some more test. These 2 are renders with about 3000 samples, obtained with about 90min reders each on a 580. In my opinion the noise is still to high for the time I spent on them, even if the situation got better.

resolution is 1200x1600

Now I was using portal and lower maxdepth (8).

Is this rendered with PMC, and what are the current settings? This could take a while to render without a lot of noise. There is almost no direct light in the scene, most light appears to be sunlight reflecting on the cabinets.

yes it is pmc... I cannot take a picture of actual settings but they are almost the same as the last I posted... just the maxdepth now is 8.

So you are telling me that reflected light slow down the scene. This means if I want to speed it up I should maybe change the setup of lighting?

[glimpse]

Maybe even changing the scene? By modeling only two wals, floor and ceiling - starting from there in order to get good lighting, fast turnaround and then gradually putting more details and texture, or shader tweeking in order to reinforce that lighting.

That might not be the actual way of how in real life it is going to look, but..sometimes artists miss the function..miss the idea why they are doing this..I mean you trying to sell, you know (at least You should know) how it suppose to look in the end..so..Fake it if You can't make it!

Vray is pretty fast in that, but a lot of artist do these open setups in order to speed up their workflow. Getting back to real life all You see in magazines, maybe no all, but a lot of stufff is posed in photographic studios to translate ideas to final product fluently, moving around artificial lighting units, reflectors etc.

Getting some inspiration, knowing the limitations of software package You're using are first two things start with.

Experiment with 'open' scene. You might cut Your times in a big portion =) at the end it's unbiased render engine.

Hi
before you try with open scene , i mean removing walls or so ,( i am against cheating ) try to render in a high as possible res. and then downscale . always helps with my indor scenes

Hi, sorry if ask here, but, i never really understand that procedures, and i think that maybe the answer to my question could be intresting to sdados too.

So here's the question: if i got a noisy image and than i down scale the resolution (like in the radiance tutorial) i'll get a much more clear result. But to produce a double resolution image i also need about the double of time or power to make it. Am i wrong? And i also need more vram in most of the cases...So how could this really help instead of make an image directly in the final resolution?

Thanks

because you must render it with the same amount of time so the resolution is upscaling and the max sampling downscaling. For example, if your render is at 1280 x 720 @ 2048 ms, for a 2560 x 1440 you need only 512 ms for reach the same result but without fireflies after downscaling the render in photoshop

ok guys sorry for the long absence, i had some day off This week I will test the new hints you gave me!

Thanks!
