Really interested in GPU using VFSU
-
HI all, hope anyone can help me.
Recently , my boss asked me how we can avail of a fast solution to rendering. We are interior design firm that does a lot of rendering and modify finishes every other hour as client demands.
I recommended him interactive rendering and he is willing to buy whatever is necessary. We are a bit conscious as to the quality of render. We sometimes print in A1 or A2 SIZE , so the resolution is about 2500 or 3000. Normally with standalone machine a high quality renders at 2 - 3 hours.
If I opt for GPU solution, How much time can we save producing the same high -res image? What graphic card can you guys recommend?
-
I use Thea4SU IR Presto AO CPU+GPU engine. 15-30 minutes per interior daylight picture of great quality in 3000 resolution (i7+GTX760). If you need even better, you also have IR Presto MC which is perfect, but 50-100% more time.
-
Hi srx,
That 15-30 mins is impressive for a high quality render 3000 res. Would you mind posting here one of example that you rendered in your hardware.
-
V-Ray also supports GPU with RT. If you stick to one of the cards at the top of this list, I bet you'll be in great shape.

You can also get a 3000 pixel interior rendering in 30 min out of V-Ray if you use DR on a network. How many workstations do you have in your office?

Render time is highly dependent of the scene itself. Having simple lighting and materials can get you a clean image in a few minutes, but complex lighting with lots of reflective/refractive materials will make render time explode. And this is true for every render engine.
So the above quote doesn't really mean anything... We would need to see the output image to judge if this is fast or not.

Some of them 50% of the original size...Of course, my goal was not to make art out of rendering, but to make fast variations of the design. For that purpose it was enough.

Those are decent renders Srx. I am vray for SU renderer but would be willing to shift (say to Thea) if that's what will satisfy my requirements in quality and much needed speed.
To make myself clearer , I attached here a sample of what we normally do. at 3000 resolution. This takes 3 to 4 hours. I wonder if by some good hardware, I could make it say, 10 minutes...
My boss would even want an instant 3 seconds full high res. What kind of machine could deliver this?
-
Can you share that or another model so we can test using Thea?
I will second the praise for Thea's speed using the Presto engine, however as mentioned above it will depend on the setup, what I see above in your meeting room render I will be comfortable to believe Thea could knock that out in minutes.
-
Yes Presto is fast!
But on Vray it shouldn't take 3-4h on decent hardware, you may have unoptimized settings.Sharing the file is a good idea.
-
I would never wait 3-4 hours for any render. If you have multiple workstations, try setting up DR, that will cut your render times incredibly. I assume you are using 2.0?
3 second full res render... uh have your boss buy a time machine and go to 2030. Although RT is getting there. Watch this http://youtu.be/k1V8h7fsYmE?list=PL

hi guys . This is my attempt to share a 100+ mb file of the model of the render i posted earlier. My files usually gets up to 180 MB.
This renders in about 1 hour 15mins in my I7- 16gb ram using vray 1.49.
I'd be glad to have somebody test out this model to see how renderers compare in terms of speed to deliver a decent 3000 render.
This is with vray data but vray elements are in a layer which is turned off initially
Check link below-- (hope the link works)

Im using still 1.49 in the office but will upgrade soon. Unfortunately Im the only SU users for now. All my colleagues are hardcore Max- Vray...
Yeah, Im sick of waiting that long..That sometimes mean staying overnight in the office. These is the era of RT, I know this shouldnt be happening...

Here is a test render with Thea Presto AO. GPU + CPU.
I must admit I didn't put a lot of work on the materials.
I let it render for 39 minutes on my modest Macbook Pro laptop with a i7 and a Geforce GT 750m.

I had some time to check out your scene. I was able to render at 1600 pixels in 5 minutes. Then with saving the LC and IRR maps, I ran a full res render in just under 10 minutes: http://www.mediafire.com/view/qqdk52aq9ff998z/full-res-test.jpg
There wasn't really anything I needed to do with the scene. I dropped in my own IES files since it wasn't included in your download. I deleted some high-poly stuff just to keep the parsing times down and help with scene navigation. For those things, I would typically use proxies, that way there's no speed hit at all.
My suggestion: get vfs 2.0 and use DR on as many machines as you can.

yeah, check your materials. You probably have things like semi-glossy reflection or refraction. Are those blinds 2-sided translucent or is it refractive material? Optimized, that should be a quick scene to do in vray. (prob 5 minutes on my hardware.. [[OK 15mins, conservative]] . I have 46 cores with DR...)
-
Thank you guys so much for your time and effort to try my model. Those are fine renders.
From my side ,I happen to work with guys who do 3ds max and whose benchmark is Evermotion,
Honestly, I have to put in a lot to even try to match their results. VFSU 2.0 somehow is getting there. I have yet to see how Thea will perform.
@Pixero, 39 minutes may still be a little quite long for my boss, If we are to use GPU,
Then He would expect something like 3 - 5 minutes.@Andybot, Yes Im immediately requesting an upgrade to 2.0 and as you say proxy the other hi poly stuff. your render is impressive for a 5 minute run, Is it done on one machine? Would I be able to cut that to say 2 minutes If I use DR on say 3 machines?

5 mins. is with DR, (46 cores, around 3.5Ghz average). If it were on one machine only, probably 20-30 minutes for the 1600 pixel render.
to get down to 2 minutes - you'd probably need over 100 cores available (or else render smaller!)

Thea Presto is much faster with a faster GPU than mine.
I know Solo has a Titan card.
Let's hope he gets time to do a test render to show what times are possible with it. -

i would really be thankful to see. titan is one solution im considering.
even for my personal use. Might as well be convinced to learn Thea
