so, I will start with this!

(click on image to see actual size)

5 min and some post

~15 mins

Ludvik Koutny · 2012-09-12, 20:54:33

Those look really awesome!

I only wonder, why scene with table and chairs took so long. Even MentalRay would do it faster, let alone Vray... :)

What were the settings for that scene?

alieneye · 2012-09-12, 21:13:45

i used production defaults for all images

about table and chairs... it is 1600x 1200 and i tried to get rid of noise in shadows (there is more area covered with shadows that in previous images) with a longer render time

Ludvik Koutny · 2012-09-12, 21:15:55

have you tried increasing light sampling? :)

racoonart · 2012-09-12, 21:32:12

Awesome stuff. I like the pink camera :D (I have a nikon :P)

alieneye · 2012-09-12, 21:44:35

now i have light samples multiplier at 4, tried 8 and 12 with same result.
and there is hard area for AA (narrow holes between planks on right chair back)

Javadevil · 2012-09-12, 23:57:43

Great renders,

The black Canon looks great, just needs the reflection in the lens.

michaltimko · 2012-09-13, 23:03:50

very good images, i like Nikon and i also own one :)

alieneye · 2012-09-14, 19:46:27

click to see full res

4K clean render

i left it rendered for night, so i can`t share the render time, probably 30-40 mins for clean image in HD

Ondra · 2012-09-14, 20:47:14

Nice render (only there seem to be some leaks in the interior, and the empty steering wheel is weird ;)), and, most importantly, nice render time ;). Its great to see that the motion blur can handle production scene reasonably.

OT//
And there is a reason why everyone presents their GPU ray tracers on car scenes. Cars just render so fast ;)

racoonart · 2012-09-14, 20:52:18

Very nice images! May I ask for your machine specs?

OT:
More important: they normally don't require a lot of Ram on your graphics card, no textures, no heavy geometry ;)

Ludvik Koutny · 2012-09-14, 20:54:58

Jawdropper! Really awesome!

alieneye · 2012-09-14, 21:00:47

it was rendered on i5 home workstation, 4K render took 6 gigs of RAM, yes, there is just one texture (but 4K) for road surface,
car body uses Blend material with 2 levels of glossy reflections on it, bridge uses Corona AO map in diffuse slot

empty steering wheel - yes! i tried to put a driver, but i no luck. i`m not good in charger driver rendering! :)

Ondra · 2012-09-14, 21:16:59

I would lose the steering wheel in that case ;) Its distracting

alieneye · 2012-09-14, 21:28:26

black man in a car! :)
yeah, maybe you`re right, i will get rid of steering wheel

Javadevil · 2012-09-15, 00:26:41

Wow really nice render !!!

Love the charger too.

alieneye · 2012-09-15, 19:31:56

alieneye · 2012-09-15, 19:55:54

with post DOF

clean render:

michaltimko · 2012-09-15, 21:38:35

awesome renders!

alieneye · 2012-09-17, 07:14:50

open black studio (faster of course)

closed white studio

Ludvik Koutny · 2012-09-17, 07:51:53

Very nice... You seem to have a lot of spare time these days... ;) Any chance you'd be willing to share setup of the carpaint-ish looking material? :)

alieneye · 2012-09-17, 08:13:13

no problem! it is very easy. but i`m limited without "shellac" mode :) I will share "car-paint" within 20 mins. Anothers image is coming :)

alieneye · 2012-09-17, 08:23:27

Ludvik Koutny · 2012-09-17, 08:37:15

How exactly does shellac mode work?

alieneye · 2012-09-17, 08:38:04

it`s like ADD blending mode

Ludvik Koutny · 2012-09-17, 09:11:23

Wouldn't that break energy conservation?

alieneye · 2012-09-17, 09:17:16

2 versions of simple-simple carpaint in the attached scene.
first - falloff map in diffuse
second - blend material with 2 materials inside. The difference between them is only in glossy values in reflection.

Javadevil · 2012-09-17, 11:01:12

Wow Alieneye,

You are knocking out some sweet renders.

I love the cups.

The perfume bottle material, the green on the inside, is it just a different material ID ? or double geometry ?

alieneye · 2012-09-17, 22:49:50

thank you! :)

separate geometry for the glass and liquid

alieneye · 2012-09-20, 08:44:23

more tests!

01. supersonic area lights! 10 seconds! (GI off)

02. Translucency

03. Torture for any renderer (Blurry refractions and reflections)

04. Car paint tests

05. Testing of corona AO map in unusual situations :)

06.

Ocram · 2012-09-20, 09:30:33

Hi Alieneye,
very nice images and shaders!

Javadevil · 2012-09-20, 09:32:34

I love the statue, really nice !

Ludvik Koutny · 2012-09-20, 09:54:50

Glossy refractions should not take over an hour, especially not in such a simple scene. Log it as a bug - "Glossy refractions take ages to render" ;)

mjkl · 2012-09-20, 10:37:16

nice test renders :)

ondrike · 2012-09-20, 11:14:10

i´m sure this gonna be best render engine ever !! fuck you Vray

Vray is pretty neat, but probably not for all.

very cool renders! lights, materials, details, time )

Ludvik Koutny · 2012-10-05, 15:41:50

Bit noisy... what was PT (GI) samples setting? :)

alieneye · 2012-10-05, 16:07:20

default, because i don`t know how it works ;)

Ludvik Koutny · 2012-10-05, 16:24:37

Quote from: alieneye on 2012-10-05, 16:07:20

default, because i don`t know how it works ;)

Lower PT samples mean more sampling will be devoted to AA, and aside from clearing edges, AA also clears DoF and motion blur, so the more significant portion of your images is blurred by DoF/Motion blur, the less GI samples you should use to devote more processing power into these effects.

On the other side, in situation where you don't use any of these effects, or use them in very subtle way, and the situation demands lot of GI sampling (rooms with small entrances where light comes through), you might actually want to increase PT samples.

Think of it as a priority defining value. Smaller number means AA+DoF+MB has priority, larger number means GI, light bouncing and refractions have priority and value of 16 being a good starting point.

In such a blurry scene like you render here, try 2-4 PT samples... ;)

alieneye · 2012-10-05, 23:30:29

thank you!
i`ll try different settings

alieneye · 2013-02-21, 20:03:26

Hi, guys!

I made the compilation of the our recent project. There was a bunch of spots (around 30) for Pantene Latin America:
artworks in different languages, different cameras and product compositions.

Everything was rendered in Corona alpha v.3, render time for 1080p frames was around 20mins for gold and 60mins for textured shots on i7 950
(actually, image was clean at 20 mins, except the translucent plastic parts). Corona DoF was used as well.

Thanks Keymaster and Rawalanche!

Nice... is this the one that got on air? :)

alieneye · 2013-02-21, 21:02:12

Yes, i think they are already in the air :)

Ondra · 2013-02-21, 21:33:20

Can you upload it to youtube/vimeo so I can give it some facebook love?

Chakib · 2013-02-22, 05:30:03

Wonderful thread ! I've really enjoyed it.

alieneye · 2013-02-22, 15:53:53

Thank you!
It is an old thread and went down long time ago :)

old thread but great one !

What processors did you use for your latest tv ad, an i5 2500k or else ?

i'm asking you that because i'm thinking to upgrade my pc config with a limited budget.

alieneye · 2013-02-25, 17:01:46

i7 950 as a rendernodes

workstation is twice faster - dual xeon E2650

buy i7 3920K if it fits your budget, you get best performance/price
and it could be overclocked

thanks, i will go for an i7 3920k and true its price is not that big.

Nik · 2013-02-26, 10:22:37

3930k maybe? It's 6 core processor. Or 3820k with 4 cores.
There is no 3920k, unless mobile version for notebooks 3920xm, but I suppose you talk about extreme performance.
Of course 3930k is more expensive and preferable :) Overclock to 4.5Ghz is easy and safe
