Here is my first corona render - basic setup, some tweaks in post pro label, and few layers in photoshop (simple postpro - vigneting, curves and brightness and contrast).
Hardware:
2 x xeon 5650 OC to 3.6 Ghz
Render time - 20 minutes.
nice render , i like it 
20 minutes? I had better start looking into a dual xeon setup!
Agentdark45 - here is something for You:
http://www.ebay.pl/itm/Dell-Precision-T7500-Workstation-2x-INTEL-Xeon-Hexa-Core-X5680-48GB-RAM-1TB-HDD-/261398665885?pt=DE_Technik_Computer_Peripheriegeräte_PC_Systeme&hash=item3cdc931a9d&_uhb=1 - price is 2000 Euro (if you are in Europe).
It’s a monster machine. I hope you will find some funds to buy DUAL XEON machine:)
In next days i’ll try to upload more wips from my old scenese.
I’ll try to prepare every scene in siimlar resolution (circa about 2000x1400) because it’s typical resolution for prints (for my clients).
It’s enough for A3 print.
the render is great
the light very good
and 20 minutes are unbelievable for this quality…
I can’t create this quality with 4 Titans in 20 minutes…and some gpu based rederers
Time to time i’m using Octane Renderer (actually in 1.33 beta version) - GTX 580 3 GB + GTX 560 TI 2 GB. But i’m using Octane with my old Cinema 4D R10 (2007 year) and i don’t have live preview renders - i have to export scene every time i will change somethin in geometry. I love CORONA because it’s 100% integrate into 3D Max. All my material from Vray are ready to convert in ONE CLICK. Only few materials needs some tweaks. In this scene i used BASIC setup in CORONA, and i remove ALL glass geometry from walls (i want to remove all possible obstacles for photos). And i put ONE simple CORONA light (rectangle) instead glass windows.
Less lights = less noise,
Less lights = less white spots
Less lights = more control over scene for me.
Tomorrow i’ll try to make night shot (one light inside IKEA lamp) - my experience tell me now, that night shots are more difficult for ALL rendereres - photos from interior lights are to weak to travel to all dark corners, and render times are increasing 3-4 times.
I’ will check this rules for Corona
Tomorrow i will prepare next interior - this time my old industrial loft. We will se what CORONA is able to do in 20 minutes with INDUSTRIAL interior:)
These render times are great, I knew it would rock on a beast of a machine. ( I use to use a similar setup, life was great then ).
Btw I don’t understand the link, but still a good price for those specs.
Workstation from link above is a “machine of my dreams” In company where i’m employed i have 2 x Xeon 5650, and my dream is to have similar or better machine at home:)
cool test
are you using PT + PT or PT + HD cache?
Corona uses the same progressive technics as the most used GPU based kernels.
With 20 minutes you can’t have this quality using one single Intel processor, the same is valid using one GTX780 or Titan.
You need more processors or a renderfarm.
Neither Octane can produce noiseless renders except you have 4 gpus and the final image is 2X the size.
Direct lighting is the best kernel for a gpu. Enrico Cerica create amazing renders using Direct Light AO and few lights, no caustics, path tracings, metropolis, etcetera.
I hope that this guy will enter in this community because he will be very surprised about Corona.
If it have Phi compatibility…everything will change.
I’m using PT+PT .I’ve tried PT+HD in SCI-FI car scene, but there was almost no difference in time renderings and in no differents in quality.
Do you have some experience when i should use PT+HD? is some especially situation (interior,exterior, product viz or other) when PT+HD is better or faster or less noisy?
About which scene are you asking (glass refraction) ?
But there is no glass in windows (i removed all obsoletes for photos in this scenes).
The only one place in this scene where is glass is left side of render - there are some thin wall made from 4 box.
yes - i know about it:) that’s reason why in many cases i’m removing glass from windows to give a photos free way to get acces into interior:) PT engine always is calculating caustics if photos it going through refraction materials. But time to time (especially for close views) glass should be turned on to get reflections from interiors environment - is possible in this case to minimalize caustic calculations?
And these GLASS WALLS - what should i change if refraction mode? which mode should i chooice?
Daily builds has some other options than Alpha 5? hm…Daily builds are only for beta testers, right? Is some way to get daily builds if i’m not beta tester?
Actually i’m calculatign this view one more time but with HYBRID mode for these glass walls. I give thsi scene again 70 minutes - we will see a difference in noise.
Thank you for all informations:) it’s very,very useful knowledge:)
Ooo, well - that’s good info:) maybe in next few days my renders will be good enough to send question about betatesting:)
