When you render to the Renderosity gallery I mean.
Rich_Potter posted Mon, 09 May 2011 at 12:12 PM
normally 1600x900 for a standard sized render for me, sometimes 800x450 if its a demonstration or that sort of thing.
vintorix posted Mon, 09 May 2011 at 12:28 PM
So when people say the "render took 3 days, 22 hours and the like they are talking about 1600x900 or something like that?
What about 3000, 4000px ? How long would that take to render ???
Rich_Potter posted Mon, 09 May 2011 at 12:30 PM
honestly, my renders never really take that long... The longest any have taken is about 5-6 hours in more recent times and that was a 4000x3000 job.
vintorix posted Mon, 09 May 2011 at 12:48 PM
I made a terrain with "Rock" as material, (the very first material in "Displacement Materials") and some transparent water over it, The terrain is 130K polygons, the waterplane only 1100. After 1 hour the 4000x2500 render was still on "0" and it said 678 h, 14 min left.
I have a fairly new Quad computer with 8GB memory and GeForce GTX 465 videocard. I was complelty baffled. I hadn't even get started yet!
As you know you can't print with less than 3000,4000px with any quality.
Rich_Potter posted Mon, 09 May 2011 at 12:50 PM
that is odd, try, just for a test, rendering it at a much smaller resolution, and see if it starts, and if not, try turning down the quality of the displacement.
Rich_Potter posted Mon, 09 May 2011 at 12:57 PM
as a thought, are you using a procedural terrain? not sure that will work too well with displacement beucase it will try and infintely refine the displacement when its closer to the camera.
Just tried the scene myself, it was a non starter with procedural terrain, but fine with standard terrain
vintorix posted Mon, 09 May 2011 at 1:07 PM
The Renderosity gallery is a great place to learn from each other. But people need to put up the resolution they rendered with and what computer power if it is to be any useful. It is like a white elephant in the room nobody dare talk about. Is it a secret?

For rendo 1024 x 768 at 72dpi
I use totally different values for my client work, usually in inches and at 300 dpi.

It will be very interesting to hear about other people's rendertimes. Don't forget the to give the computer spec! It is at the start, at the very beginning of the project.

Well that doesn't tell us so much does it, for the ones iín inches and dpi was perhaps some simple logos? Without seeing what that is rendered size tell nothing.
Here is a render from 00AngelicDevil00's "First render of 2011", rendertime was 58 hours.
http://www.renderosity.com/mod/gallery/index.php?image_id=2155735&user_id=577773&member&np
But she doesn't tell what was the rendersize! What I want to know is, is it possible to render pictures of such complexity in 4000x3000? And what will the rendertime be?
thefixer posted Mon, 09 May 2011 at 4:54 PM
36" x 48"
2625 x 3450 pixels
300 dpi
Is that better for you?
I can't show the image because it's for a client and showing it before it's published would be against my contract with them.
Can't tell you the exact render time either but it was less than 5 hours.
It's all a moot point anyway, the atmosphere you use, the type of lighting you use will all make a huge difference, not to mention displacement and textures etc. the variables are too great to make comparisons.
TBH, if a render was going to take me 58 hours, I wouldn't bother, I'd look to make some changes to bring it down, you don't need long render times to make a good picture and you don't need them to make work for clients that pays money either..

thefixer,
I hear what you are saying but 00AngelicDevil00 is one of the best Vue artists of all time. I don't think she would be rendering 58 hours and didn't need to.
The time is a moot point as you say yourself, as long as we don't SEE with our own eyes what is rendered.
If it was a practice to publish rendertime and size in the gallery everyone would benefit. Until proven otherwise, I don't believe 4000x3000 versions of 00AngelicDevil00's pictures is practical for anyone without a Disney renderfarm.
vintorix posted Tue, 10 May 2011 at 12:44 AM
Another beautiful day!
Thank you for the overwhelming response to "Subject: What resolution do you use".
So the time and size will even in the future remain a secret.
I have a pretty good guess though!

Well that is open to different peoples views on art I guess, personally I really like some of the art this person creates, some I don't, but I would consider other artists better than others.
Each person will have different views on what great art is.

I keep my renders down to 1024 or 1280 so that they fit on monitors. If everyone here has 2560 then I'll keep that in mind when rendering my final stuff.
My renders can take from 20 minutes to 20 hours depending on what materials I use and how much of it is in view. I try to bake textures in advance to speed up rendering.
vintorix posted Tue, 10 May 2011 at 2:22 AM
Thatnk you Shawn, for you information. I think you are pretty mainstream in rendersize. How is your Pythons studies going?
Rich_Potter posted Tue, 10 May 2011 at 4:06 AM
I just tried your scene, It starts rendering after a few seconds for me, but gets absolutely killed when it gets to the terrain. I think you render settings might be a little bit too high on the User Settings in my opinon.
Although having said that when I got to the terrain it also absolutely killed the render time, but im not sure why? If i start another scene and use a terrain with the same material and same resolution it goes much faster.
Im using a 6 core 12 thread xeon e5645 by the way.
vintorix posted Tue, 10 May 2011 at 4:11 AM
Thank you Rich, your informationi is most helpful. If my settigs are to high, what particulat parameter needs to change? You see that the atmosphere is the simplest possible.. This is like a criminal investigation!
ShawnDriscoll posted Tue, 10 May 2011 at 4:15 AM
I started on it a year ago. Then had to do some C++ for someone. Then got hooked on other hobbies. Python is still on my things to learn list. Proably by the time I sit down and do it, we'll have Vue on our phones.

The render won't budge from the first terrain bucket. This does indeed look like a crime of some kind. :)

What did you do?
?
ShawnDriscoll posted Tue, 10 May 2011 at 4:35 AM
Something in the procedural material for the terrain kills things at 4000x3000. 1024x768 was walk in the park. Check the terrain and make sure it's not going into an infinite loop damn near just for each grain of sand the camera thinks will be in focus that hi-res. OVER-KILLA!!! :)
Did you plan of any depth of field for this render? Or motion blur?
Rich_Potter posted Tue, 10 May 2011 at 4:39 AM
I turned down displacement quality, light quality, put the settings on final rather than user and sent it on its way, 8% now but you get some funny spikes at the top from dodgy displacement.
Rich_Potter posted Tue, 10 May 2011 at 4:42 AM
turning off displacement speeds things up imensely, i suggest that is the issue.
ShawnDriscoll posted Tue, 10 May 2011 at 4:48 AM
For the material "Rock" I unchecked displacement. Now it is crusing again at 4000x3000. Yey. Murder solved.
Oops. Solved already, by Rich.

ShawnDriscoll posted Tue, 10 May 2011 at 4:54 AM
Don't forget the PSD.
Just as I thought, rendering at 1024x768 with the camera close to the terrain material halts Vue also. The fractal and displacement in relation to pixel is the culprit.

vintorix posted Tue, 10 May 2011 at 6:19 AM
Well thank you! So it was the displacement that was the culprit. But the mystery is not solved, as other terrains with the same material and the displacement not turned of works, but never mind!
After I disabled the displacement and added some minor enhancements it turned out like that (rendertime15 min!),

Observe the water. The water texture has nice foams on it, but if I turn on transparency the foam disappear. The only way to have both (ie to have the cake and eat it) is to make two renders of water, one transparent and one with foam. Then I can in Photoshop exact decide where I want foam and where I want transparency. (not done yet)
I am using a reference, and the Vue scene is positioned exactly as the ref.
Rich_Potter posted Tue, 10 May 2011 at 6:25 AM
since you are using a image for your river, and it has the foam already included, the best option, in my mind, is to make a transparency map based on where you wan the foam to be, so black (or white?) where the foam is and the white (or black?) where the water should be. but the one you want transparent should be a grey really since it shouldnt be 100% transparent.
vintorix posted Tue, 10 May 2011 at 6:39 AM
Yes I could do that but that would implicate more work to ashive the exact degrees of transparency/foam wished for. Still I wouldn't mind the extra work if I thought it would make me able to render the whole enchilada with all elements and eco-systems + real atmosphere etc at 4000x3000px in one sweep. No chance of that!

bigbraader posted Tue, 10 May 2011 at 10:50 AM
I usually render at 2000 - 2400 wide and use custom settings, and rarely go over 10 hrs. of render time.
Renders of 20 - 30 hours or more are usually the results of lacking skills/knowledge, unless they are HUGE.
About Drea's render mentioned above, it shouldn't take that long. Sure, there are some low density clouds, which is notorious for producing heavy renders, but still... I've also noted that she often uses the Vue presets, e.g. the "Broadcast" mode, that's not particularly clever. She may be one of the most popular Vue artists, but certainly not among the most skillful. An example of a skillful and great Vue artist: Artur Rosa. That's a whole different league IMHO.
vintorix posted Tue, 10 May 2011 at 11:38 AM
Well I think taste and style is difficult to discuss..
I put Drea as #1 here at renderosity, but that is only me. The only one who matches her is perhaps someone at cornucopia3d, like Daniel Respaud. Drea lives together with Michel Rondberg aka da1imu who also is a good artist, albeit not in Drea's class. But he is a competent engineer - together they form a strong team. Quadspinner Dax Pandhi is a good friend of the couple that live near.
Last, technical knowledge is more than Vue. Proficiency in a highlevel modeler like 3ds max or Maya is important as is zBrush and VRay and others. There is more between heaven and earth than Vue's function editor.
Edit:Check out a typical profile for a professional CG artist,
ChuckEvans posted Tue, 10 May 2011 at 3:43 PM
Well, doing what I can to bring the thread off topic...
What is the displacement for and if using one on a procedural terrain can't be done (if that's what happened), that would seem to suck.
I would hope Vue could handle 12 x 16 (inches) @ 300 DPI for a suitable sized piece to hang on the wall with ease. By, EASE, I mean done in single-digit hours.
vintorix posted Tue, 10 May 2011 at 4:19 PM
12300 = 3600
16300 = 4800
You wont get a quality render in single-digit hours using any kind of beautiful atmosphere with a resolution of 4800x3600px
300 dpi is more for coffe-table books and art magazines like. For a painting that hangs on the wall and meant to be seen from some distance 150 dpi is sufficient. 2400x1600 is a more manageable resolution. But if you want a larger painting, say 32x24 inches, we are back to 4800x3600px again.
What I advocate, is that even as a beginner you should acustomate yourself to work in the larger format. It is a completly different workflow and if you don't do it from start you never will get into it.
ChuckEvans posted Tue, 10 May 2011 at 4:39 PM
Thanks for your reply. :)
I mentioned 12 x 16 as something big enough to hang on the wall and would hope I could do it without waiting for days.
I was looking into Vue as an aid to the paid work I already do. In that regard, it would need to be at least letter (8.5 x 11) in (near) size (for full page ads) and CD jacket/case sizes. Two weeks ago, I had to design a standing banner that was 32 x 81 (counting 3 inch bleed) @ 300 DPI.
I might render some stuff for fun for monitor viewing but ultimately, I was hoping for some quality print.

"I might render some stuff for fun for monitor viewing but ultimately, I was hoping for some quality print."
Exactly so. Who wants to have 300 pictures made over several years representing hundreds if not thousands of hours of toil which are good for nothing except printing postcards? Even if you don't plan to sell anything it is still pleasant to give away paintings to friends and family. And if the unbelievable happens that people begin to take an interest in your work and there is a demand, what a catastrophe if all this paintings are too small!

Absolutely !
Now, I'm not "putting on airs" or anything because I'm certainly a smal-time designer. I do "word of mouth" Photoshop work but I design for a small starup record production company. And Vue might be useful in generating something for use.
And I design for the US Government at the moment (retiring in a couple of years).
Personally, I don't have what it takes to become "big time" anyway--I'm not special. So worrying about "being discovered" isn't a concern...LOL. However, I might like to have some Vue-rendered "Kinkade-ish" landscapes on my wall some time wink.
