Gab's gallery , update 05/05/2010

Post here your finished projects. Your work could form part of our gallery!

Man, that´s... incredible :shock:

You have to tell us a bit how you did that: illumination & textures are simply awsome.
The best work of your great gallery.

Congratulations and five stars render for me.
You know how to make Blender + Yafaray work ;)

Thanks Arkinauta !

For the underwater light i use displacement mapping + a spot like this :

Near the crab there is an area and 3 spots :

For the textures , most of model use displacement mapping ;).

I will upload an example soon .

Gabich, we have enabled attachments, we were thinking about you when we got it implemented :D So please use it! Some images in the first missage have already dissapeared.

Great work, great balance of exposure in this last render, have you tone mapped it?

I think those images deserve to be in the Yafaray gallery :)
Thanks for the illumination screeshots.

Congratulations, Gabich. Superb work.

That is awesome :shock:
I am very curious to see your render settings.

Thanks guys !

It is a mix between a ao render and a photon mapping render

Yep , the ao render is tonemapped .

Some news renders !

Hi Gabich.

I'm always happy to look at your work, but I think the whiskey colour is a bit off, it should be lighter and more orange.

(Maybe you could do a selective render and composite, as it is probably not worth spending another 30 hour render on it.)

Apart from that, the lighting is lovely, is it all external, or do you have fill lights inside the room as well?



EDIT - I see you have the same cloth sim problems in your restaurant scene that I encountered; it is so difficult to get a sharp edge where the edge of the table should be - http://www.yafaray.org/gallery?g2_itemId=533

Thank you Stoneage.

Yes i'm agree with you , the whiskey have a strange color ,i will change it soon with a litlle post prod .

For the light , there is no light inside the room but an area near the windows and some area on the other side for the door( there is a sun + sunsky and 50 depht :D ) :

Yes , the cloth need a high level of subsurf but the polycount of the scene was already high ...can't have more polygons because blender crash .

30 Hours for the interior rendering? Holy Cow.
That is a very long time. Is there no way to shorten
the render time with Yafaray?

It seems that the rendertime is getting close to when you use Indigo or LuxRender.

I compared a scene from Vray to Yafaray and VRay was multiple times
faster. However it also had a different selection of GI solutions.

Curious if those might make it also into Yafaray.

cekuhnen: notice that the interior render was 2400x1300, and without a hint of noise. I challenge even maxwell, let alone indigo or lux to do that.

But you are right, Vray and MentalRay are for reasons unknown to me much faster at PM.

Oh I did not see the size.

Yet 30 hours hui. I am just impressed both, quality, and used time.

Isn't Maxwell pretty accelerated now? Just curious. Based on what I was
told is that in the recent years it gained speed drastically. But that can
be very subjective.

VRay for GI does I think not use Pathtracing and Photons anymore.
Also no FG. Irradiance map for primary bounce and light cache for secondary bounce
is what I think works quite fast. In on of their documents they stated that they
still support photon but describe it as outdated. Light Cash is supposed to replace Photon Mapping.

Well I am no programmer so I cannot really judge those opinions.

Gabich

do you have a simple scene you rendered with Yafaray I would try out with my VRay and Blender? I would like to see some comparision. I tested a VRay scene with different GI settings and noticed also one picture can easily take up to 60 minutes - brute force and still be very noise. I assume brute force is similar to path tracing.

Just playing again with some other modes.

Well, I did comparision, here are two examples (Ladder and RedRoom by Xelptic).

Both scenes are interior, so harder light conditions to calculate.
My goal was to render preview picture in low res, but with low noise/grain visible, showing well light behavior even in small parts of the picture.

Scenes are very simple, where comes to geometry count, I've tried to keep materials and lighting as similar as possible.
Both renders use only sun light with sky model (same conditions as far as exporters allow)

Yafaray uses Photon Map mode - I think it's only one that suits here, where it comes to speed/quality ratio.
Vray uses Irradiance Map for first bounce and Light Cache for second bounce - phenomenal speed/quality ratio.

Overal conclusion: Yafaray gives more noise/artifacts in longer render times :(

I really like Yafaray, it is very good, free and OPEN renderer, but it is too soon to comparing it with Vray (commercial) which is far more efficient renderer.

Comparing this two is like comparing version numbers: Yafaray is 0.1 (302M?) and Vray is 1.6. (at this point there's more sense to compare Vray and Kerkythea, maybe?)

Main weakness of Yafaray comparing with Vray are (in my opinion):
- no advanced light computing algorithms like irradiance or lightcache. Photonmap with final gather are fine but:
- no advanced image sampling algorithms like DMC in Vray (with it's treshold can go really fast without noise)
- no ability to freeze light solution (no animation)
- no network rendering

Don't get me wrong, I believe that Yafaray will get all those features soon and I REALLY LIKE this software (you can actually use it in commercial projects with quite nice results). This is "now" and how I see it.

Looking for your (constructive) responses.

ps. oh, theres one important thing to mention: rendered pictures were saved as HDRI or EXR and postprocessed to match brightness/contrast. Also "very light" bilateral blur were applied (the same settings with every image).

It's a wonderfull Gab's world :D

I love your work.

One day, I'll use Yafaray for my renders. One day, I promise you :wink:
