Something to keep in mind is that there were VERY few textures used in that demo scene, with lots of raytraced shiny objects.

Re: Octane render
Hmm Arnold long way for production? I'm not sure but from what I saw, having more predictable results with faster tweaking times with Arnold is way more production ready than anything with MRay.

Re: Octane render
Thanks guys! While testrendering with unified sampling, I found that I get fastest turnaround if I take the time to manually set sampling for glossiness or AO or lightsamples to a reasonably clean (e.g. not too noisy) result first, then rely on the unified sampling and pixel filtering filter to clean out the result. Hooked all AO nodes to the Renderglobals by setting rays to 0 for each shader´s AO node, then set it globally. Glossiness samples in the floor and the chrome came out better this way, I´d describe it as wheigting the input for the unified sampling according to scene demands. One caveat I found with the above is that regardless of the realtively quick turnaroud for large, homogenous surfaces, geometry edges will look noisy unless one cranks down the Cuttoff Parameter to very low values (in the range of 0.03) to prevent edge jagginess/crawling noise. That is something that reminds of VRay when using a similar (even if not at all identical) approach to sampling... Most people leave the AA filter default of 1.5 in Vray, which pronounces this even more (2 would be better) that´s why I chose gauss 3 in mR, to blur the edges a bit more... I´ll happily see how low I can push this, thought. First, it´s trying irradiance instead of envAO for a comparison. Cheers, tim On 26.02.2013 04:21, Jason S wrote: True.. with unified sampling, it's better/faster to let it take care of crunching through the noise (and crunches only if necessary) Though in my experience, helping it a little (area lights at ~2, AO at ~4) yeilded faster results, yet maybe I was missing something. I heard Sony Imagework's version of Arnold does have a unified Sampling equivalent. Nice image though! On 25/02/2013 5:10 PM, Ciaran Moloney wrote: Looks great! You should be able to drop all of your shader samples (including AO) right down to 1. Then push up the max samples and quality in unified sampling. Keeping shader samples at a minimum will allow for more efficient sampling of the scene, only where it needs to be done. As much as I like Arnold, I do miss having an adaptive sampling solution.

Re: Octane render
I'm no way an expert MR ! I'm doing very little jobs, with very small power in computing. An image rarely exceed 5min to render. I rarely go the photorealistic route (although sometimes I wish). Its rather a mix of NPR and other tricks that makes the pic looks acceptable. The classroom example here doesn't match my everyday reality. 45min ?

Re: Octane render
That's pretty far from my typical day with MR, it's definitely production ready. With that said, I do appreciate that you reach a good result quicker in Arnold, and the feedback is typically much better, but I'd have to say that Sitoa crashes Soft more than MR does. MR is very predictable, and very works very well with passes and general tricks you need on a daily basis in regular production. Many scenarios are faster to render than Arnold due to its biased optimizations. On Tue, Feb 26, 2013 at 10:22 AM, Mirko Jankovic mirkoj.anima...@gmail.comwrote: Hmm Arnold long way for production?

Re: Octane render
I don't do archviz, so no classroom renders for me either. Typically, I try to keep frames from going over 10 minutes, usually go for shorter, but sometimes you just have to spend up to an hour on a frame, in those scenarios Arnold would probably be more efficient. But then again, we rarely do full-frame CG, mostly integrating objects into plates. On Tue, Feb 26, 2013 at 11:58 AM, olivier jeannel olivier.jean...@noos.frwrote: I'm no way an expert MR !

Re: Octane render
Hi Sven, thanks a lot for jumping to my rescue. As far as I understood them, the guys are just really, really happy to have Arnold. Of course, it shows :-) Didn´t take them personal but welcome your stepping in, it´s true, it´s fun and a challenge to play with the various options and also more rewarding when the result looks at least somewhat aristically pleasing, even for tests. I really don´t mind when the guys compare it with Arnold, actually, I do as well compare what mR, VRay or Arnold offer... Cheers, tim On 25.02.2013 21:10, Sven Constable wrote: The rendering from Tim shows some artistic driven and clever combination of other techniques as a different approach to brute force GI. He doesn't used FG or photon mapping or IP. So it doesn't reflect mental rays capabilities in photorealistic rendering but instead a other way around. Render the scene in arnold or maxwell with AO only and it will look the same. Of course no one would go the AO-only route to achive photorealism.

Re: Octane render
Looks great! You should be able to drop all of your shader samples (including AO) right down to 1. Then push up the max samples and quality in unified sampling. Keeping shader samples at a minimum will allow for more efficient sampling of the scene, only where it needs to be done. As much as I like Arnold, I do miss having an adaptive sampling solution.

Re: Octane render
True.. with unified sampling, it's better/faster to let it take care of crunching through the noise (and crunches only if necessary) Though in my experience, helping it a little (area lights at ~2, AO at ~4) yeilded faster results, yet maybe I was missing something.

Re: Octane render
I thought exactly the same, because of Autodesk's idiotic documentation. It is a fundamentally different approach to sampling for MR. As I understand it (smart people, plese help me out here!), MR formerly simply added or in some cases, multiplied the number of samples cast from each ray hit. Say you have a raytraced shadow-casting area light with 3x3 samples, and a glossy surface with sampling set to 16, and adaptive AA max at 2 (which is 4x4=16 samples per pixel) -- for a given shading fragment (basically the intersection of a ray with a triangle), in a single bounce, you could end up with something like ((3*3)+(3*3))*16*16 = 4608 samples being needed just to return a value for a single ray. I'm sure I'm oversimplifying and probably have the math wrong to boot, but basically, every time you added something that required multiple samples -- glossiness, motion blur, DOF, AO, soft shadows, bump maps -- you ended up increasing the number of samples MR would take at any given point, regardless of whether they were neededto achieve a correct result. Unified sampling essentially looks at all the samples being called for by every shader that affects a ray intersection, and somehow (math again!) balances (and perhaps shares?) the sample values returned as they accumulate, so that only as many samples as the user sets as a maximum, or fewer, if the quality (think of it as 1/noise) threshold is reached, are ever taken. Or you can think of it as magic. But it can result in HUGE improvements in render time. Sometimes.

Re: Octane render
That actually looks pretty nice (even without bouncing) and actually looks alot like what my own trick looks like without FG / AO bleed (no muddy corners) to which I made backflips to get it to render under 5 minutes, but of course there was no glossy relfections and such.. There was an other post showing an image using env AO.. does that just mean enabling AO's environment sampling? Using a 360 degree env map of the scene? For an interior with say a window in the center of one wall, wouldn't the environment sampling act as if the window as infinitely far away uniformily for all objects in the room? Which is ususally fine for exteriour lighting but. anyway, thanks and nice work! On 23/02/2013 7:33 PM, Ciaran Moloney wrote: yeah, it's pretty cool.

Re: Octane render
Probably 9hrs, too... I didn´t optimize for speed but clean glossirendering and have pretty high settings for each material´s AO node, mostly 32-48 samples, add the glossiness to that and you see time running away. I´d think that having the option to use the same AO node across multiple materials (like in Maya, connecting via the hypershade) may be worth a try to see if that brings down rendertime. I´ve around 10 materials, that´s 10 AO nodes each with a very large falloff distance set... The glare output shader could also be nuked, I think. Posteffect, quicker.

Might also be that i have no idea why this is happening and i'll just do another render with more accurate settings and see what happens :)
Re: Octane render
Your last post looks realy cool after 1hr. My internal version uses nearly the double of the time as the standalone, Don´t know why... I believe to remember that there used to be (or still is) an issue where it was taking considerable amounts of CPU time to copy the updated internal image from the renderer to the Softimage render window. Afaik this only affected render windows but not the Render region (or vice versa?) Maybe this is slowing your internal version of the render down? Have you tried updating the Render Window less frequently and see if that speeds up the total render time? I think I also remember that copying one large chunk of data to the window is slower than copying many small chunks. Stefan
Re: Octane render
@Steven: I can change the samples to max 64k, but haven´t tested it. I think when i double the sample, in this case to 20k, it should noise free. It depends from scene to scene. Indoors with less light sources are always slower. An outdoor render will be faster... @Toonafish: Sorry, not available to download. Must integrate the environment which is set in this image via the sourcecode. Than i will start a closed beta... @Stefan: Have tested some things and found the problem. The problem is, that each mesh is added to a groop. If you have 20 meshes, the group has 20 input pins. Each pin will need some time to evaluate or whatever. When i merge the whole scene in one mesh, so that i have only one pin in the group, then i have nearly the same speed as in the standalone. One problem here is, that each mesh can only have one uv map. An other problem is, if you have an envelope, the whole merged mesh must be submitted again for each frame. This is why i use multiple meshes, i check if the mesh has an envelope, then i submit only this mesh. An other nice feature here is, i have a check if only the srt is animated/changed. If the srt matrix is changed, i send only this matrix to Octane to make the calculation on the gpu. So you can move, scale or rotate each mesh, without to submit it. I can also send more than one matrix to Octane. Octane will then dublicate the mesh with the matrix information. It´s a scatter. But here is the price the renderspeed. Hope that Otoy will find a solution to speedup the process... Stephan 2013/2/20 Stefan Kubicek s...@tidbit-images.com Your last post looks realy cool after 1hr.

Re: Octane render
did you color correct this? i like the color... and i think the glossy reflections came out great! i am still struggling with some noise in reflection and glossy. can you share your arnold scene? ill post mine tonight, it was certainly fun to do. ya this is worst case for arnold. i imagine when talking about purely casting as many rays as possible, a gpu renderer at this time win against a cpu bound renderer. i imagine if ronald would post his rays per pixel we would see octane is tracing many times more. he said his graphics card has 1500+ cores vs his cpu threads at 12. thats over a hundred times more, assuming its a linear relationship.

This scene is an almost worst case scenario for Arnold fwiw. Indoors, main lighting is from only windows, glossy's, reflections, refractions, DOF, MoBlur. How much of that is Octane doing btw? It's interesting to play with for those reasons and it's definitely possible to make it look good... it's just that the render times go up a bit because of the increase in sampling.

Re: Octane render
gne... you took my quote out of context :) i imagine when talking about* purely casting as many rays as possible*, a gpu renderer at this time win against a cpu bound renderer its not subjective... octane has access to more hardware. so what i am saying is, arnold would preform similarly if it was using a machine with 1500 cores. we would set the sampling really high and be done in 10 mins and it would be silky smooth. i still think arnold is the better overall choice. s On Tue, Feb 19, 2013 at 5:00 PM, Gene Crucean emailgeneonthel...@gmail.comwrote: Yeah even win is soo subjective with this though.

thanks for this stephan... so 2:04:07, two hours or two minutes? it says 16000 max samples, can you describe what that means in octane? and more generically? does octane count the rays per pixel? ie. the amount of rays fired for the entire ray tree in order to generate the color for one pixel? if so what is that count? s On Tue, Feb 19, 2013 at 10:22 AM, Stephan Woermann swoerman...@googlemail.com wrote: Maybe a little bit late.

Re: Octane render
alright, here is my try on the scene. I tried to get it to a level of the 7h maxwell render. the maxwell render was done on a i7 2600K @ 3.4GHz and mine was on a X5680 @ 3.33GHz. the difference factor is about 2.75.

Re: Octane render
it's so clear to me that I'm using arnold that I sometimes forget to mention it. sorry about that :/ settings depend very much on how you approach such a render. here is a short overview on how I did it: the one with DoF needs more AA samples so the way I do it is to raise the AA to 10. Then I dial every aspect (lights, diffuse, glossy) of the sampling separate until I have the same amount of noise in each of them. I start with one sample and raise it until I'm somehow satisfied. Mostly 2 samples per component is enough and if we have heavy contrast in the glossy component I raise that to 3. Then raise the AA slowly to the expected noise level. In this case to 20 to really smooth things out. So here are the sampling settings: AA: 20 Diffuse: 2 Glossy: 3 one QuadLight in front of the windows: 2 Sharper Distant Light: 1 Raydepth for all components to 1 but diffuse to 4 the one without DoF doesn't need such high AA samples so we can rearrange the sample settings to something like this: AA: 6 Diffuse: 7 Glossy: 6 one QuadLight in front of the windows: 5 Sharper Distant Light: 4 Raydepth for all components to 1 but diffuse to 4 here is another one without glossy rays. this one brings the render down to 27min. it's the same setup as the one with DoF except without any glossy rays shot: http://xsi.jankin.com/dump/ClassRoom_a.0001_27min.jpg Cheers Vladimir On Sun, Feb 17, 2013 at 2:26 PM, Steven Caron car...@gmail.com wrote: @vladimir, arnold correct? indeed its good, some of the other renders dont have the proper light/shadow on the ground. i think its because of the techniques being used on the windows. the 'lightplane' mesh, if its being used as an area source it tends to give improper shadowing on the floor. so talking about technique, whats your setup like and sample settings? all my renders still come in around 2hrs with too much noise still. s On Sun, Feb 17, 2013 at 8:16 AM, Vladimir Jankijevic vladi...@elefantstudios.ch wrote: alright, here is my try on the scene.

Re: Octane render
Vladimir, there are still problems with the AA - look at the upside down chair legs and window frames. Did it really take you only 30 min of tweaking each lights/diffuse/glossy samples test, then AA samples test, if the final render took 44 min? Where you rendering the tests at smaller rez? @Tim, there is no type of AA sampling selector in Maxwell - except a slider for softer vs sharper looking AA. Slider goes from 0 to 100 and I used 60 (the default). This can be changed during or after the render. The difference is subtle, so below I've saved 3 different versions - default 60, 0 and 98. We use a proprietary AA sampling technique which was a big part of V2 of Maxwell :) @Emilio - there isn't really that much you can do to optimize a scene like this in Maxwell or any unbiased renderer that doesn't have a built in hard bounce limit. This type of scene is one of the hardest things you can throw at them. One of the things you can do if you can however is not mix normal emitters with sun or skydome since these two types of emitters have very different strengths and Maxwells optimisations don't work well in these cases. Here is the classroom scene with Maxwell materials applied (ceiling emitters are hidden): https://dl.dropbox.com/u/32548637/Classroom_test.rar Here is another example with Physical sky this time, with the ceiling emitters hidden. I've also made the floor glossy reflective instead of just diffuse which should add to the complexity, but the render time was only 3h for this one to reach the same sampling level. There are some small more noisier areas on the floor - those are in fact glossy caustics from light reflecting from the low glossiness chrome legs onto the glossy floor. It's nice to know you have this subtlety if you want it, but you can turn indirect or also direct caustics off in the render settings to speed things up.

Maxwell is amazing, the quality of light is impressive, thanks a lot for those tests Mihai From: Mihai Iliuta Sent: Saturday, February 16, 2013 8:05 AM To: softimage@listproc.autodesk.com Subject: Re: Octane render Hi there, Hopefully this will be in the right threadhere are some classroom tests with Maxwell Render. Ronald, I just took your scene and applied Maxwell materials trying to match the look from your tests and for the lighting I just used Skydome. My machine is an i7 2600K @ 3.4GhZ, and according to our benchwell test (www.maxwellrender.com/benchwell) your machine should run it in about 10 min, mine took 14min, so 40% slower.

It's true that it takes a much longer time to get a super clean image, but usually a small amount of denoise is enough instead of waiting... So to compare the 7h render would take about 5 hours on your machine. the 2h render matches in noise your Arnold 1.33min render and would take about 1h20min on your machine. For the 7h render I turned up the intensity of the ceiling lights using Multilight to match your render (but they would never look that strong in reality if you expose for daylight, unless you want the electric company to come arrest you...). Quality wise, perhaps in my not so unbiased opinion, there is more life in the Maxwell render, mainly due to not limiting bounces. I don't understand what the point is to have only 2-3 bounces of GI because it starts looking dead and like an AO pass - greyness everywhere. Look especially in the chrome material, radiator area, in between the wood boards on the desk. All these things add up in my opinion and other tests will show it better. I prefer to know I'll get a render that looks and feel like a photo, not a render that looks like yet anotherrender. Also most of our users will take up 2GB of RAM just for loading their textures, no matter the resolution of the render and many want to render at at least A4 print size which is about 3500px wide at 300dpi. Finally, maybe we should maybe do a test with thousands of particles, hair, DOF, MB, sharp caustics??? Bring it ON!!! wlEmoticon-smile[1].png330.gif
Re: Octane render
Great ! A Maxwell render. I agree, quality wise 7 hour render rivals the Octane 45 minute render. Rendertimes are higher, that was to be expected, but it's nice to see some proof. You are right I think, a lot of the renders don't look as realistic due to low diffuse bounces or use of occlusion. I think this Maxwell render is the first one that is better quality then the Octane render. And the lighting looks better then my green room too :-) How many bounces did you use ? I left Octane at the default 16. - Ronald On 2/16/2013 8:05, Mihai Iliuta wrote: Hi there, Hopefully this will be in the right threadhere are some classroom tests with Maxwell Render.

I ask because I often use this setting (all the time for previews, often for renders) in order to minimize the amount of idle proc time while the last couple buckets finish, but have been told lately that it's actually a time-waster since the renderer has to resample all the bucket edges.

Way to go, octane! ;) http://www.imagefront.de/tmp/classroom_mentalray3_8.png Shading, lighting and tweaking took me much longer than 30 minutes but I'm on 2011. No unified sampling and I also had some crashes with satellites that seems to be fixed in newer version of mr. I guess the rendertime on just the workstation would be around 1hour. The workstation is faster than the nodes on the farm and there is also some network overhead when using satellite rendering but anyway, rendertimes aren't bad. I always liked mental ray. cheers, sven
Re: Octane render
Mostly to avoid cores idling, with large tile sizes you could really be wasting time, especially for something that only occupies a small part of the image, or a really detailed patch that's left to last running on a single core after everything else is finished. But it's part of my optimization routine, so occasionally I increase the size. Never heard of the extra sampling issue, can't imagine it would over-shadow the 1:8 ratio of cores rendering simultaneously though, unless it's a scene with extremely even detail level.

That would be swell. But I think we'd also might have to include setup time then.

Re: Octane render
Nice job there! I find that it doesn't match the Octane version in terms of quality (not your fault): a) It looks floaty. That's just the problem with FG. You'd need insane settings to get the flawless contact shadows of an unbiased renderer. People like to combat that by using ambient occlusion, but usually the result looks terrible to me, with dark corners everywhere. b) Sampling noise of a biased renderer looks unnatural (see the reflection on the table at the very left). Unbiased renderers otoh have very organic noise, so often it's fine for there to be some. I've used Octane many times for still shots and even for animations. Setup times are short, render speed is good and the quality is great. Plenty of features are still missing (such as motion blur), but once the Softimage integration is ready it should become a real option for those who don't like to use an external renderer.

Re: Octane render
When using high AA samples (which is necessary for DOF or motion blur) I believe you can pretty much keep diffuse samples down to 1 or 2. You have to oversample a lot for the DOF, and this AA oversampling takes care of diffuse areas as well. Also, for this scene with the large windows you may get away with 2 or 3 bounces.

Re: Octane render
That was some good advice, thanks. I Reduced the diffuse samples to 4, diffuse rays to 3 but had to increase AA to 20 to get an acceptable amount of noise. The quality is about the same as before but the render time was reduced to 1h:33minutes. Also got rid of the sampling errors by clamping the sampling values. But still much more fine noise overall then the Octane render, so I'm rendering one with a diffuse sample setting of 6. https://dl.dropbox.com/u/4271217/Arnold_Classroom_AA20_DiffSamples-4_DiffRays-3_1h-33min.png So far Octane is still the winner by a landslide.

Re: Octane render
i think we all knew that comparing straight ray tracing speed, without textures, displacement, subdivisions, and deformation motion blur... octane was going to win. i mean thousands of processors that are great at doing this type of work compared to ~12 more generalized processors, octane takes advantage of the gpu and arnold doesn't... winner octane!
