AgX in Blender 4.0. It's coming, are you ready?
HTML-код
- Опубликовано: 9 июл 2024
- In this video we look at a new rendering feature in the upcoming Blender 4.0 that deals with color management. Blender 4.0 is gaining a better view transform function called AgX which is more sophistical than Filmic. That's what this video discusses. Both Filmic and AgX functions were developed by Troy James Sobotka.

I kind of prefer this educational style more over the over-charismatic jumpy forced fast forward style that many creators do with their blender videos. Keep up the concise and precise explanation. 👌🏻
Sadly everyone is on that jumpy time quick saving 1 minute video train. Like I like detailed videos explaining to me like an adult or some Ted talk lol.
@@vilmfilm It depends on the subject. I really appreciate 1 minute videos when I just need a concise answer to my question.
Your videos are killer. It’s hard to find great Blender content this in depth aimed at an audience that already has a good understanding of the underlying fundamentals of 3D/Blender.
I’m watching despite having the most basic understanding
This was by far the clearest, and easiest to understand, explaination of colorspaces I've ever seen on the subject - thank you!
Your channel is a gold mine
I have never seen such a clear and well demonstrated explanation of what gamut amd view transforms are.and seeing the shift between them really makes it so apparent. Having ALL of that color data there, even if desaturated, is mind blowing to see. It is so clearly all there.
Thank you for explaining this. No one (I know) can explain this kind of technical data better than you. I'm not sure if anyone else is even bothered or knows how to explain it. This is a great service to the Blender community.
Yes 🙌 totally agree ! Brilliant and cristal clear !!! Bravo !!! Et merci beaucoup !
Damn, this fixed all color problems I've had on my renders. Thank you for sharing this! You're the first I've seen talking about this.
At 17:22, if you use the ACES from Blender, the OCIO config send with Blender, it's not the real ACES, not match (too desaturated). The one with Blender is mapped trought the view transform inside a REC.709 profile. I use the real ACES 1.2 using OCIO variable and it's closer to the standard sRGB but with a better control if not clamped in indirect (ok, the six color problem still here but can be solved in comp). I'm not so quite happy that Blender devs choosed AgX because the principal problem that we are not using Blender in studio is because the lack of industries standard and here, I think, it's the worst error they made. AgX is nice to eyes directly and ok, less work to do in compositing, no more six color problem but if you light your scene correctly and you keep the rules of "no color in real life have a saturation other a value of 0.95" all is good. The same problem is present with USD, this last one is imported, not referenced using the USD layer system that is the base of the USD goal, so here again the devs close the door to use Blender in studios... And I say that because I like a lot Blender and want to use it in studio but choices like this put Blender again at the side of the road. Maybe I'm wrong and AgX will become an industry standard but I think not because it's not only a color system, it's also a LUT and in VFX / 3D movies and series we need to match color directly with a MacBeth table and not spend time to estimate it because a LUT (look profile) is inside your render and need to no wich one. Great video on the subject, thx.
I'm not sure what you mean by not real ACES? Presuming you are referring to the "ACES Linear" colour space, that is the ACES 2065-1 (AP0 primaries) not AcesCG (AP1 primaries). If you are loading ACES Linear output from Blender as AcesCG then it will look desaturated as they use different primaries and AP0 has a larger gamut. I do agree adding AcesCG as an input space within the Blender default OCIO would be a good idea though but the beauty of OCIO is you can modify to match your needs as an individual and as a studio. Studios often don't use the default OCIO set ups anyway, they set OCIO via environment variables.
As for VFX and Macbeth charts it doesn't clash with ACES at all. AgX is not a colour space it is simply a view transform. The view transform doesn't need to be applied to your output from Blender, export linear. The scene data will be the same and you can still use Aces interchange colour spaces if you wished then use AgX for your view transform in Nuke or whatever software you composite in. It won't affect matching Macbeth charts at all as you are matching the colour **before** the view transform is applied to your image data whilst it is still linear.
It's best not to think of AgX as an ACES alternative or competitor. ACES is an encoding system that happens to have a view transform within it. That view transform isn't ACES (as much as people think it is). You can still use ACES in your pipeline and then opt to not use ACES pre-packaged view transform. AgX is a better alternative to ACES ODT not the whole encoding system.
Hope this helps.
@@llennoco It's exactly that (AP0 vs AP1 and of course the rec.709 profile forced in the Blender 3D viewport). I use AcesCG in Blender for all (color wheels and co), so I have an AP1 trought all my pipeline. Not solve the rec.709 hardcoded profile in the viewport (background image in camera) but in blender compositor it's ok and in Nuke and Davinci too. I'm working only with exr file in AP1 linear in all my softwares, less gamut but constant in all softwares. And yes, AgX is better to the eyes directly, but not well incorporated in differents softwares, so a bit tricky right now to have a pipeline with it.
Every video of yours is incredible, they are the right amount of beginner friendly info to in-depth info without being overboard. The many examples you provide in various scenarios and demonstrating what's happening and why this/that is better... just amazing. Thank you so much for making this content and I look forward to every video you make!
I've been using AgX for quite a while now, and I'm really excited for this update.
Yeah, this is an important update that could be overlooked easily. It's nice that it's an official thing now.
Very nice explanation of a hard to explain topic. It would be fair to add that both Filmic and Agx are developed by Troy James Sobotka.
Thank you for that. I've added that info to the video description for proper credit.
without this demonstration i don't think i would have figured out what the difference was alone, thank you for the showcase of filmic vs AgX difference
This level of understanding of how technology works is just truly fascinating to listen to even for someone who is only a fan of 3D and tech. What a great content
Finally blender goes toward realism without spending money on other program
Chris, let me take the time to give you some feedback here in the comments. I'm putting it under your latest video, but it applies to all your content so far.
It has been an absolute joy to go through your material up to this point. Even though I'm experienced enough in Blender not to "learn new stuff" per se, I absolutely love to watch this kind of thought-through, well-paced, clear, and quality-driven content. Many years ago I spent my time in Cinema 4D and used Maxwell Render as a plugin. With a photographer background, I really appreciated the artist-friendly approach that Maxwell allows: model to scale, describe the material properties (Maxwell gives you great control over Fresnel and falloff), set up your camera as you would a real one and just press render. No tricks-just beautiful light (if you wait long enough 😇). Since I moved to Blender years ago, while I like Cycles, I've always missed that 'chef's kiss' details in the plausible natural lighting that I feel I got from Maxwell. While I haven't jumped into Blender 4 yet, what I'm seeing in AgX, I feel that might bridge a big part of what I've been missing. The larger dynamic range and the natural desaturation in the highlights will do wonders for photorealistic rendering.
It is an absolute crime that you have only got around 6900 subs. But PLEASE stick around and keep doing what you do. I would really love to see more from you using Blender 4 with its new technologies going forward. I love the look of your renders and would really like to see more videos focusing the balance between model quality, texture complexity, and lighting setup.
It breaks my heart that "commercial success" on RUclips doesn't follow the quality of the content, but it's hard to change. I hope the artist in you can find some amount of consolation in the fact that there is at least a small community here that really appreciates this type of content. I will try to get my act together and contribute too.
I’m going to share this video with colleagues who use Blender. Will do my part to support your channel 👍
Nice! I thought this was going to be a difficult video, but you explained it so well! And thanks for talking about ACES too. I thought it was the gold standard already.
I personally hope they decide to support the ACES pipeline fully in the future. But for now not. You can installed ACES since Blender uses OpenColor IO however.
This was my question through the whole thing! It's doubly confusing as Unreal's "filmic" is an ACES transform (with a *lot* of knobs to tweak), so I was really surprised to see that Blender was using an SDR transform.
Color management is complex for sure.@@SimonBuchanNz
I can't wait for blender 4.0 to come out
This is some information that I didn't know I needed to know. Thanks for the very descriptive explanation.
Wow! The explanation of the 6 color problem and what AgX does is really well done! And the other examples as well!
Nothing but a banger! 🔥
This is going to be a game changer, awesome video!
Thanks for the detailed explanations and great examples. Awesome!
wow, what a exellent explanation!!! great video
This is gonna be a game changer. Blender renders always had that "Blender look" (not in a very good way) because of filmic VS other industry softwares like Maya or 3dsMax which use ACES. Now content created with Blender (even by beginners) will have by default a much more pro look, apparently even better than the competition.
This will literally change the colors of how Blender art is looked upon for the better!
This is a fantastic video, thank you for going through and explaining everything from the top too! I learned a ton from this video, it was a great watch ^^
Wow! this was so in-depth! I love it!
Excellent video! Your videos are the most informative out there
Love the style of this video! Very concise & informative. Subbed 👍🏾
I just had a render client provide me with a file needing AgX and it's the first time I used it. Definitely retained some of the blown-out sky in his render and slightly muted things but an effect helped with that. You did a phenomenal job in explaining the sRGB problem as for many of us that's all we know, and how things like AgX move beyond that limitation. Great video, subbed.
Yes!!! The channel is coming alive!!! This guy also was the Strata 3D master that first got me into 3D back in the day… so glad he joined the Blender team!
Glad they are adding a better view transform. One thing I noticed when trying to manipulate my renders in a photo editing software was that lack of dynamic range and presence of saturation. Worked to my advantage as I was not making anything that was meant to be subtle, but I can only imagine how annoying that could be for professionals making high quality renders for commercial applications.
Best explanation of AgX that I've seen online. Thank you so much for your work.
What a masterclass, thank you!
Excellent overview!!!
Fantastic explanation. Thank you for taking the time to produce these very informative and interesting videos.
Wow, this was so informative. I've always struggled to understand the view transform but now see how much my renders could benefit from it. I'm excited to try AgX now. Thanks so much!
AHH this was such a useful video, thank you 😁
What a great explanation, thank you so much for these videos!
Very well presented. knowledgable video series on the new features in 4 colour management. Thank-you!
13:45 the explanation and examples are apt, precise and concise... AgX is mind blowing
OMG dude what a great video. Thank you sooooo much.
Amazing videos... your level of understanding rendering is on another level :)
That was really well thought out and informative. I don't see this quality too much, and I rarely mention it even when i do see it. Great job! Subbed.
I feel like Im back in college watching your videos. Your teaching me about thing that I was completely unaware! You broaden my world bro!
That’s the best explanation I have seen on this topic. Nice to be watching your content again after I left strata behind so many years ago.
Thanks for sharing! Your videos are incredible, really showing in practice how it works, excellent explanation, I'm your fan!
Thank you! So informative ❤
this is a high tier video of blender information. i hope you get 100k subs soon! thanks a lot!
Solid stuff as always 💥
I’m treating this video as a college lecture, so much knowledge poured into making this!!!!
Crazy concise presentation. Really perfect, and an absolute rarity. 👍
Appreciate the wonderful content. Extremely insightful.
Thank you so much for your hard work ❤️❤️❤️
Excellent video! Thanks!
great video man! i find it very nice how you kept it informative, yet simple and easy to follow. i also like how you talked about ACES, which i was going to ask about, but you stopped me right in my tracks so good on you for anticipating that 😂
thanks for sharing the knowledge, and keep up the awesome work!
Wow this is going to be amazing!
Great explanation, thank you!!
Extremely high quality renders and video, thank you. So many people don't understand the amount of time, work, planning, execution it takes to create this high quality of content. I applaud you, Christopher. (I've been doing 3D since around 1995, and creating tutorials on RUclips since 2009 on anther channel not connected to my personal account)
Dude, You've done an amazing job at explaining everything😀! I'm always scared by all these color transforms and stuff because they always go over my head and seem very very complicated, but you explained it very nicely. Though, I didn't understand everything, I learned alot 😀! Thank you so much for the amazing video & sharing the knowledge! Blender 4.0 is very exciting and amazing :D
🙌🙌🙌 so amazing! thank you for all the knowledge you share with us 🙏
Great video! Learned a lot! Fantastic explanation.
Your content is a gem 💎 thank you so much.
so well explained dude!
Thanks for this overview, very helpful.
Amazing content! really nice explanation about such an important detail. thank you!
Extremely helpful and insightful information! Thank you very much.
Wow. The example with the solid colors is mind blowing. Stunning!
Thank you better dude!
Super amazing clarity assisting bringing colour + rendering info into light. Off to explore AgX.
Thank you for the explanation, it was quite clear and I'm excited to try it in Blender 4.0
I have noticed this problem since 2014 and I was trying to learn computer science and programming to create a color system since that period, but because of the war in Gaza since 2014/2016/2018 unfortunately, I was not able to do that, but now when I leave Gaza and my circumstances improved, I discovered that someone had preceded me in this 😂😂😂 Sorry for my bad English
GREAT EXPLANATION! Thank you very much for your time!
Alright, I'm sold! The difference in that scene with those three "neon" RGB pipes and spheres is staggering.
realy helping. thanks!
Great film! Very helpful.
Love your content, very authentic in nature. Btw I just noticed your channel banner has a typo for the word practical!
Thanks for the catch, I've fixed that.
It's the first video from your channel and after watching this i have to subscribe because the video was very informative and awesome.
Thank you for this wonderful explanation.
Fantastic explaination and examples. I've been using AgX in Blender, Substance Painter, and Fusion for a few weeks. It really is extremely good in practice. Great to learn Blender are including it in 4.0, but it's very easy to install right now - so I'd advise people to chuck it in and have a play around.
This is an excellent video 👍
This is extremely helpful.
Thank you for this fantastic video.
Great job explaining the concepts
You are technical grand master of Blender ♥♥♥
Very nice and easy to understand intro. Thanks.
I've been looking for a relationship between the three of them, thank you very much for your explanation
about time!
Very amazing and in depth video, the technical explanations were very understandable.
Great tutorial!
Thank you so much..!!! :)
Thank you for the Video. Well explained.
Compiling my top 20 go-to RUclips TUTs - you're def way up in there C3D! - Many thanks for your education:) There's a buzz I get when someone like yourself explains something in way that even I can understand, I love learning and understanding how things work. Short cuts/add-ons are great if you know your stuff, ie when in a production environment - can save time. But if you're learning I say, don't get too distracted with all the unnecessary add-ons - instead do the spade work in blender vanilla and understand how to get there/problem solving etc. In the long run you will save more energy and time than any add-on can provide.
Very cool!
Thank you for this awesome video!
Quick question. In your Blender viewport there's a sort of "display linking" button enabled on the upper right. I never saw it before. What is it for?
Yes, it's a fantastic add-on I can't live with now. It makes it so when you switch from one viewport to another, the are matched up. It's frustrating when you go from one viewport to another and have completely different camera and shading. Someone wrote an addon to sync them up. I did a quick video on it with a link to the addon. ruclips.net/video/jSnLLPQhDsc/видео.html
thank you very much!!
Thanks amazing explenation! Woow
Thanks A Lot Bro ;)
Top notch explanation and step by step comparisons for semi-laymen like myself >> it seems AgX gives you a 'log profile' effect so that you have all the colour information to allow for freedom of post processing decisions >> which will make for some fantastic 'next level' image renders from all the super talented folk out there... excellent work👌💯👀🎯😎🌟
Great content!
Great explanation.
