Hello!
This is my latest personal project, just for fun.
Trying to improve on materials and overall realism.
C&C are welcome :)

Congratulations, they really do look like photos!
-
Beautiful renderings, and design as well. congratulations!
If I am supposed to give any comment, it would be related to the background only. it seems maybe, just a little bit overexposed? But, even though, they look very charming

Thank you very much! :) Yes, maybe, I usually expose everything like a real camera and don´t mind if somethings get overexposed :)

Hello daniel.reutersward
Nice work.
There is no aberration of objects, for example the 04_1.jpg...a good perspective!

Yep, they look really great! Good job :)
Plus the spaces also look quite warm... i mean like someone could actually live in there without getting crazy :) I quite often see renders of spaces that look interesting and realistic, but a nightmare to live in :)

I'm loving the warm vibe. Really nice looking renders!

you cool

Thank you very much! :) Good to hear that someone could live like this without getting crazy! I wanted to have enough stuff but not too much so it gets chaotic :)

Haha nice, don´t know what they are called, gif? And thank you! :)
you cool
Thanks!

Spectacular!
Materials look awesome.
Mind sharing some info about your workflow - lighting exp ? Is this HDRI or regular Corona sky/sun ?

Sure! In this scene I used an HDR from CgSkies, really good HDRI´s there! If you have any other question just ask :)

Ok then, hope not to be too nosy ;)
Could You go more in depth into settings (more or less default - or something altered) ? I mean in the last couple of months many myths (dont know what is right and what is wrong) about settings emerged, would be awesome if someone getting good reults could clarify those things a bit :)
Any portals used ?
Are the glass panels in windows thin surfaces or thick geometry ?
Could You please show some more coplex materials setups (whichever You think are more complex) ?
And last thing - Your machine specs and render times per frame (no of passes would be great!)
Sorry if I'm too nosy, but those renders are simply eye-candy!

No problem :)
No portals were used (perhaps should have tried to see if the noise disappeared faster with some portals).
The glass panels in the windows are thick geometry (boxes).
The close up pictures were rendered on my home computer (Intel i7-3930K @ about 4Ghz) for about 1 hour each. Rest of the pictures were rendered on my work computer (2x Intel Xeon E5-2667 @3,3Ghz), one render per night so I´m not exactly sure when the render were finished.
Regarding settings I´m not actually sure what´s wrong or right, I don´t really care about render times and I´m only focused on quality and I´m kind of lazy regarding optimizing render settings.
I changed HDCache Record Quality to 1024, GI/AA Balance to 32 and Light Samples Multiplier to 8 (everything else on default), just to be sure that everything would be noise free. I did some test with default settings and my settings and the noise disappeared at the same amount based on time. But my settings might be too much or wrong! I think number of passes were somewhere between 100-200.
As for materials, I´m not sure if any of the materials are more complex than another. Is there any specific material you would like to know about?

beautiful!
too many books, no iPad?...:)

When you are not sure, just leave settings at defaults... they will get the job done ;)

Thanks! No iPad no :)

Thanks! So my settings didn´t make any difference? Or maybe it made the render slower? Is there no benefit in upping the settings?
-
Amazing work.

In Corona, there's not really such thing as upping the settings... There's just changing balance of sampling, not increasing it... what you did with your setting was increasing amount of GI sampling and direct light sampling at the expense of AA sampling... You need more GI sampling and direct light sampling in scenes with difficult direct light and indirect light paths... such as very small windows, lot's of bouncing before light gets to the rendered surface, and so on.
Since your interiors are not that difficult, defaults would do just fine. If you increase GI/AA balance and LSM, you may get cleaner surface, but worse antialiasing. There is not much fine geometric detail or textures in your scene, it will probably not do any harm, but you should keep in mind that antialiasing also takes care of DoF... so for shots with significant DoF effect, it is sometimes wise to actually decrease GI/AA balance, to get more samples for AA and therefore DoF. It is also not hard to figure out if you should. If focused areas clean up faster than areas out of focus, then decrease GI/AA balance. If focused areas clean up slower than areas out of focus, then increase it ;)

@ Rawalanche - thank You for explaining the 'magic ;)
One more question if I may - what solution is better noise wise - solid geometry glass in windows or thin geometry ?
Portals or no portals ?
@ daniel.reutersward
Thank You!

fastest possible solution with correct results is single plane, twosided (thin) mode, portal checkbox enabled

Thanks for the information, really good to know for future renderings! :)

Thank You Ondra.
Do normals direction matter in this case ?
-
no, they dont matter at all

Great lighting and perspective.

Sorry, at keymaster....what do you mean by "portal checkbox enabled"? cos i cant find a dialog box like that yet.

Cool Render's Wow!

its is in material options, in advanced tab

Photos of a good design are always welcome...

These are great visuals and really capture a warm and welcoming room set. Can I ask what HDRI you used from CGSkys?
Many thanks :)

Thank you very much! Sure, I actually used a HDR from Cg-Source (might have written wrong before, sorry about that), but the sky I used is called "cloudy_sun44deg_0086-01".
-
Thanks for the update on the HDRI :) Did you build the room using a plan or just free-styled the whole design? Can you tell me a little bit more about rug material in the lounge please

Heh, I wondered if it was typo....because CGSkies is like the...worst trash possible, while CG-Source is heavenly. In fact, no other should even be considered at all, if CG-Source was 10points, everything else would be 1-4 top, not more.
And I've tried every on the market, hundreds...

I used a floorplan for an initial idea for the size of the rooms and the rest I just designed it like I wanted. Regarding the rug, I made the mesh with marvelous designer and the material is a bitmap and a color corrected version of that into the displacement slot.

I actually have had some great results using CgSkies so I´m a bit surprised! But yeah the results using HDRI´s from different sites can be pretty different in quality.

You were so good you got on the Evermotion frontpage twice :D

Hi Daniel, Excellent renders! I am trying to switch my work flow to corona. I'd appreciate if you could throw some light about your scene setup-
1. Can you please explain a bit about your Exposure and color mapping settings(EV, Contrast, Highlight Compression and White Balance) ?
2. Secondly, the thing i am not able to understand in Corona is how does light intensity parameter work ? Suppose i need to brighten/darken the scene, do i need to play with Exposure and color mapping settings or with light intensity parameter values ?
Thanks!

Hello!
Thank you very much! I will try to answer your questions as good as possible.
1. For this project I used the "CoronaCameraMod" and adjusted the exposure like I would have adjusted a real camera. I raised the highlight compression to 3 to get rid of some blown out areas and left the white balance and the contrast at the default values.
2. I don´t really know if there is any difference if you raise the Exposure settings or raise the light intensity. I usually raise or lower the Exposure settings until I´m happy with the result and leave the light at the default settings (when using HDRI´s), when using artificial lights I change the lights intensity to match with the HDR.
