You can also use "Crypto mask" render element with "Denoiser" in Frame buffer to select and denoise specific object from the scene. For example, only the rims and the chrome bumper and the paint of the car will be intact.

[@JonasNoell]

Yeah that’s right! I would love if there would be some option to not only just exclude objects from denoising but also define areas where your denoising is maybe 50% and some others where you would have 100% denoising and so on. At the moment you can just completely exclude objects from denoising. But nonetheless I think no other render engine even supports that 😀

I really love your Vray techniques... Always blow my mind about it.

[@jimmwagner]

Love that fastback! Also this is a week times tutorial. I’m testing render settings for work right now. Thanks Jonas!

Very helpful tips, as usual! Always learning new things from your videos, keep them coming!

[@tausifkhan2189]

As always very informative and very helpful for real time uses. ❤

Nice tips on IPR settings!

[@ExacoMvm]

Idk what happened to V-Ray over the years but it's definitely slower than the competition, especially it's GPU scaling is so bad to the point even CPU renders some scenes faster meanwhile in Cycles the GPU is consistently 10-20x faster than my CPU. I've did some CPU render testing and V-Ray even managed to lose against Arnold in somewhat medium complexity scene w/ VDB/SSS, Scatter, etc.

[@JonasNoell]

I did some tests and it is true that the raw raytracing speed in earlier versions of V-Ray is a little bit faster. Talking with Chaos I was told this has to do with more advances features (Denoisers, Lightmix, VFB Compositing, etc.) that have been added and using those in combination will increase the speed to reach the same results. I think it is somewhat true and somewhat wrong marketing :-) Speaking about comparing V-Ray with other GPU engines I did some simple tests and initially VRay GPU felt much slower compared to FStorm and Redshift. But with the tips from this video about the IPR settings that changed the result and V-Ray felt much faster compared to Redshift though still slower than FStorm. It's just a simple scene though, so results may vary on more complex scenes. You can check this test here: www.jonasnoell.com/downloads/vray/fstorm_redshift_vray_v002.mp4 (v001 is without those optimizations). I think V-Ray scenes can be insanely optimized if you dig into the details. Much more than other render engines would allow you. So it is hard to compare. From my feeling is that in terms of CPU rendering V-Ray is king when it comes to features vs. performance vs. adjustability. But that is my personal opinion :-)

[@ExacoMvm]

@@JonasNoell Interesting, thanks for the info! And yeah I agree V-Ray CPU is great overall especially with all those nice artist features and it's probably the best CPU renderer overall, too bad GPU still lacks a lot of core features and the performance isn't the best especially in low light such as interiors. You should also check out Cycles X ( Blender 4.0+ ), it obviously lacks many features but in terms of engine I think it's really great performance/accuracy wise at least from my experience. It can even beat Octane's Direct Light kernel in terms of speed especially w/ Path Guiding and Fast GI Approximation enabled.

[@JonasNoell]

@@ExacoMvm Cool, I will check out Cycles! The last time I did though it was lacking a lot of basic features like just a separate VFB with some basic functions to make it really usable in production from my feeling. But I will give it another look. 🙂 For V-Ray GPU I think most features are supported by now or? I didn't really run in too many unsupported features yet to be honest, but haven't tested it extensively yet. Just the main annoying thing is that normalmaps and bumpmaps seem to work very differently across the engines.

[@ExacoMvm]

@@JonasNoell I think Blender doesn't even have IPR, it's simply integrated in the main viewport which is highly customizable anyway even if you use Octane or Redshift so it's not a big deal, there's also keybinds for things like region render, etc. Probs that's one thing I don't like about Blender is that everything feels "hidden", as there's no easy to find button or UI stuff for commonly used things. Last time I've used Vray GPU in Maya it didn't support basic things like texture on mesh lights also I had some issues with refraction calculation for underwater product shot which was very off and only switching to CPU solved it also if you look at the GPU Supported features there's still a lot of quite useful things that's still unsupported or partially supported.

[@JonasNoell]

@ExacoMvm Yeah ok then it sounds like it’s still the same like when I tested it last time. I think they should focus on integrating those basic features, especially if you say the renderer itself is so good in terms of quality and speed. But just rendering through the viewport without IPR and not being able to interactively check your render passes and VFB compositing would be a huge slowdown or annoyance for me. But I will check it out again 😀

Hi Jonas, can you please make a video explaining Vray GPU Render settings? Also, what is your suggested: 1 - Low render setting 2 - Mid render setting 3 - High / Final render setting for this VRAY GPU engine

[@mamalikhakzad24]

god i love your clean workflow. it`s very satisfying.

[@3DLASHnet]

Awesome as always. Thanks Jonas. I think people with the most value gets the least recognition

[@JonasNoell]

Haha its alright, I have awesome Patreons who support what I do! But a few more subs would be awesome though :-D

[@waqaranayat8083]

​@@JonasNoell you deserve a lot of subs on your Patreon

thank u for the best vray videos

[@ss54dk]

Press vray Rendering "start/stop" button has a huge lagging is the vray big problem, and sometime will crush. Choas need to focus this to make a better user experience.

[@educafe132]

What about the image filter? Which filter render fast

[@JonasNoell]

I just stick with the default and didn't really notice any drastic differences in terms of speed to be honest.

[@Jason1989A]

Hi Jonas, it is recommended by chaos not to use any AI denoising for production render, due to inconsistent results across render elements - instead using the default V-ray denoiser for final production renders. you can also try a different preset for example the mild preset if you don't want it oversmooth the more noisy areas and so on. Do you use the Intel Open image Denoiser for production quality rendering and if so do you experience any issues?

[@JonasNoell]

I know it is recommended by Chaos to use their native denoiser in animations but in practice I've had much better results using the AI denoisers (in particular the Intel denoiser as stated in the video). It always depends on your usecase though, if you have super slow movements and your base rendering is VERY noisy so that the denoiser has to pull the majority of the work then you indeed might run into issues where there is flickering across the animation as each image is denoised separetly creating variations. In my line of work (VFX, Advertisement, Automotive) I rarely ran into those issues and in 99% of the cases prefer the result of the AI denoisers compared to the native one. Using the presets in the Chaos denoiser often times results in areas where you get very strong denoising in certain areas bordering other areas where there is suddenly no denoising at all once the noise falls under a certain treshhold, creating uneven patches across your images. I find the AI denoiser to create much better results preserving more details and having less of the "oil painted" look the native V-Ray denoiser suffers from extensively in my opinion. What is yours?

[@Jason1989A]

Thanks for the feedback Jonas! very helpful, well I was only using the AI denoising for test rendering, but since watching this video and chatting with you, I am now switching to using it for production rendering, I do know the oil painted look using (V-Ray denoiser) you refer to and it is not ideal and causes issues and in most cases not wanted so you end up turning down the opacity quite a lot due to loss of details. Looking forward to having greater results using the open intel denoiser, thanks for the great content Jonas and as usual looking forward to learning more from you! 👍@@JonasNoell

[@JonasNoell]

​@@Jason1989A As said its always good to know the benefits and limitations of each option and then chose the most suitable option for your specific usecase. I'm not saying the VRay Denoiser shouldn't be used, I just say that for my usecases and in practice I got better results using the Intel Denoiser without experienceing much of the proclaimed downsides. But your usecase may vary, just try it out and see what gives you the better result 🙂

[@rumblerabbit5064]

Well done explained Jonas! Do you use you 64 core PC just only "at home" to produce your interissting YT Vids ? Or do you work also as a freelance ? And just a question.. Could you share your workstion setup ?

[@F10F11hm]

Amazing! Is it possible to export all the VFB settings with all kinds of adjustments made, render an animation sequence in pure linear fashion and then apply them later in AE, DaVinci Resolve or Nuke? Or do you always render animations with VFB changes "burned in" if you know no further changes will be made in post?

[@JonasNoell]

You can export a LUT and render out the linear image. But you can also burn it in if you don’t want to go through additional post processing. So both ways work :-)

[@F10F11hm]

@@JonasNoell Awesome, thank you! Will check!

[@user-ip4to1sp3u]

Keep grow up 🤞🤞

[@dancherry814]

Thanks for another great video @JonasNoell Just wondering if you would change anything for rendering animations as opposed to stills?

[@JonasNoell]

Since I mainly do animations those would be my standard animation settings. So in combination with a denoiser this for me is a good balance between quality and renderi time. If you do high res stills and rendertime is secondary compared to quality I would probably bump those settings up in my final rendering, because why not.

[@dancherry814]

@@JonasNoell Thanks for the explanation. I hope you don't mind, but I have a follow up question: is the denoiser temporally aware for animations? The documentation notes to use the standalone denoiser tool to get this frame blending.

[@JonasNoell]

@dancherry814 Technically the standard V-Ray denoiser should be used for those situations. But I don't like it as it creates unrealistic and oversmoothed results in my opinion. So in practice I use the Intel denoiser in animation all the time. If your base rendering is not too shabby and the denoiser doesn't have to do too much it works pretty good and is almost unnoticeable with some subtle film grain on top.

[@dancherry814]

@@JonasNoell Thanks again for the info, and taking the time to reply. Much appreciated!

[@Ricardo-de9ju]

Not really impressed by GPU performance response. Redshift can provide way better performance on large scenes. I pretty sure Chaos is working hard on it, but even they don't give much attention to GPU yet, because it's way behind the competitors.

[@JonasNoell]

Really? Where is it behind? It supports most of the features that are supported by CPU rendering in combination with the most advanced framebuffer that any renderer offers. So would be curious to see what Redshift can do that V-Ray GPU can't? I did a simple test rendering the same scene and V-Ray seemed to perform faster than Redshift (while being outperformed by FStorm) www.jonasnoell.com/downloads/vray/fstorm_redshift_vray_v002.mp4

[@Ricardo-de9ju]

@@JonasNoell I'm talking about GPU performance, Vray is slower. Now, certainly Vray has an awesome FB which no one can beats and so many other features.

[@Ricardo-de9ju]

​@@JonasNoell Forgot to mention, progressive mode is by no means intended to render, only coarse previewing. Only bucket mode can be optimized for faster render times. The tool is great but UI/UX guys got fired I guess, haha. And it has poor documentation IMO.

[@blckops712]

Redshift also looks plastic. Vray is given 100 gi bounces out the gate and far more depth. As someone that professionally has used vray, octane, redshift I will tell you right now redshift is pretty meh. If all you care about is speed that's fine. But vray gpu isn't far behind and giving better results. There's a reason bigger studio's still use vray and Arnold for vfx.

[@bobrobrules]

So get a 4090? Got it. joking aside. this is awesome. The ipr is so slow on my laptop.

[@JonasNoell]

On laptop GPU rendering is actually king because of a lack of really powerful laptop CPUs. So if working from a laptop i would only try to focus on GPU rendering 🙂
