Blender 4.2! New tone mapping, the Khronos PBR Neutral Tone Mapper. 

When I heard about this being implemented in Blender 4.2, I was so happy I kept having problems with color consistency with sRGB textures since I do product design and product visualization in Blender Thank goodness for this new view transform

I learn more things from this channel than the official Blender channel! keep up the good work!

Thanks Chris, just experimented with this myself and have to say the results have been amazing when compared to the AgX maps.

Fascinating, this is great news! As you said, this will be great for motion graphics areas where aligning to specific hues and saturations is more important. Lots of good demos to visualize this too.

Thanks for a great video! I had a project where I needed to render yellow glass and it took me hours to understand that because of AGX the part that is transmitting the refraction (not reflection) couldn’t handle a tinted refraction, I had to go back to filmic to solve this

Chris Tyler is a blast from the past , I’m sure I’ve read some of your early work on rendering on older 3d software! This is an excellent visual and oral to help understand the new tone mapper .

Thanks Chris for bringing good news! That's exciting!

You are such a brilliant explainer!

This is such a great educational video

Tank you for the video !!! I fully missed this news.

Finally! The video I was waiting for.😁

whelp cant wait till kcycles 4.2 comes out.. between eevee next and this it's going to be really nice for my workflow

Incredible knowledge as always 👏♥️

Thanks for the tutorial ! It is really helpful

thank you, very instructive and straight to the point

Chris, thank you very much for the comprehensive explanation!

The Klingons have done it again. (had to through in the star trek reference :). Great video explaining color management!!

As always. Informative and clearly explained video. Thank you.

Great knowledge! thank you for sharing

Well, I'm sold! Great job describing this vital feature of Blender 4.2. I can't wait for it to come out of Beta!

Thank you!! Very interesting and very important information!

Thanks for bringing the update to limelight, I might have missed this impressive change.

Wonderful Sir

TNX. like your explanation :)

Sometimes people (including me at some point) confuse Tone Mapping with LUTs. Maybe because LUTs are also "mapping" colors but its purpose is mostly to create a mood (except the conversion LUTs). Where's as Tone Mapping, as you mentioned, is strictly about converting out of range colors to fit in a defined space.

This is the one I was looking for

Always interesting videos

Thank you for the video Chris!! I am still boggled by the fact we got 2 new Tone Mappers in the past year, and still no ACES in sight- Meanwhile theres 1000 Comment Forum Discussions about "hOw AcEs Is InAcCuRaTe" (Yeah i am talking about you Troy S) when the only thing we want is being able to play within ACES Pipelines

You are the best teacher I’ve found when it comes to learning new color spaces and tone mappers. I’ve learned nearly everything I know from your videos about AgX, Filmic, and now Khronos! I just want to ask though, what would you recommend for additional resources for learning more about color spaces, tone mappers, and achieving the best-looking results in various cases?

Probably a stupid question, but are there any disadvantages to this new tonemapper vs Agx? Are there any scenarios where this couldn't be the default?

Seu canal é incrível e nos fornece informações valiosas! Obrigado em nome de todos!

like always.... damed.....nailed ....again. 💪💥🗯🔥💭❤💨🕊

Thanks a lot. I seems that I will use mostly Khronos instead of AgX.

Well described, will come in handy every now and then, but I've been loving AGX, I'm more cinematic based though, good to have options though for sure.

at 6:48 the Khronos color management doesn't seem to solve the issue of smooth transition from one color to another. Maybe my eye is failing to see the improvements somehow. Because I am seeing banding still persisting. But you explained it nicely otherwise.

Interesting! Maybe there's a worflow to be made where you use the Khronos render to drive the HUE of the AGX render in Photoshop - that way you get best of both world ...

👌👌👍👍

Thank you for a great video, just saw you have a typo in the title for "Neutral"

I need this in my life life... right now! :O so, when is Blender 4.2 coming out?

PHD level teaching

Great video again Chris. I think Kronos is the future and will replace all alternative Color Spaces in Blender in the dailie work. I don't think someone will ever use the others again. Of course it's always better to render in raw format and make the postproduction later. But I think Kronos makes a lot of things easier and other modes obsolete.

Would be very interested to see a video on the new Thin film feature for the principled V2

That’s a big step in the right direction, and it seems to work well on these small product renders with simple light setups. However, when I tried it on an interior scene with sun rays coming through and falling on the white walls, with a lot of reflections and glossy highlights on the furniture and marble floor, I have to say that although Khronos is much better than AgX (not to mention Filmic), it still unfortunately diminishes those highlights and rays... However, it does work very nicely with colors, maintaining the original saturation. Than again, I guess it's called Khronos PBR Neutral for a reason. Hope, one day it all will result in a good universal tone mapper.

Oh no. Here comes yet again new update videos that makes me want to switch to beta...

So, should everyone use Khronos for everything? What are its weaknesses, or where would you still see a use for something like AgX, rather than Khronos?

I think AGX is superior for more realistic scenes, the new khronos one has a more disney pixar feel to it, perfect colors in a vacuum where the colors don’t experience any shift. Perfrct for products and animation but maybe not if you are trying to create a cohesive room or environment where agx might help blend things better and then you just apply a hue of color on top of the image.

The improvement between Khronos and Agx is bigger than the improvement between Agx and Filmic.

Sorry if this is a silly question, but for those of us that work in EXR none of this matters since we're in a linear color space, right? Are you implementing any of these color space transforms in your pipeline?

Khronos will be better for some types of scenes, but AgX better for others. It will be nice to have both.

Am i wrong for thinking that this looks "too good"? The slightly washed out bright colors of AGX look a bit more realistic and pleasing to the eye in my opinion. Perhaps this isn't about realism, and in these cases color preservation is more valuable.

Thats nice, but usually color soutions are rather like too short quilt, and if you cover your head you have cold feet, so what are the downsides of this transformer, where are the weakest points?

Standart + Filmic + Agx = Khronos )

What color space is Blender used for scene deferred rendering? Is it ACEScg or the biggest brother ACES AP0?

Downloaded 4.2 and I cannot get Color Management to show the differences from AGX, FIlmic, or Khronos, seems to be broken.

would rec2020 make khronos look worse than with srgb? logically i don't think so, but i need certainty haha.

Not sure but seems everything I render in 4.2 is worse quality than in 4.1. EVEE now blows out the contrast more and Cycles looks muted and im using imported settings from 4.1

another OCIO?

I'm sorry but i think filmic still looks best in all the examples. Khronos seems to just blend the worst elements of AGX and Standard: As colors get brighter they become oversaturated and then become undersaturated, with very obvious delineations, while filmic is the only one that keeps the saturation consistent throughout the gradient, at least in appearance. Does it look faded? Sure but it'll be alot easier to add a simple curves on top of that than trying to resaturate only the highlights in AGX and Khronos.

I always thought Agx is wrong, those massive saturation loss is way too much, I couldn't understand why many thought this is ok. ACES desaturation is way less and much more realistic. With Kronos we now have the opposite, no saturation decreasing at all. More usable in everyday work but it may be too saturated at the very edge.

That's great news! I always had a color problem, be it with my monitor, or filmic / agx. I understand that colors aren't supposed to be saturated much, but when I ask for 255 maximum RED color, and I get a desaturated one, it gets very annoying. Now I can actually make my diffuse map a full 255 RED, and do zero corrections on the lighting and composition!

when will blender cloth work like a normal turk?

This looks great! AgX invariably produces terrible colors in every project I've tried to use it in.

You define the restrictions and downfall of Khronos "PBR" Neutral in your first few sentences. "...designed to do this in neutral lighting conditions...". What is neutral? Surrounding and context matters immensely when READING an image. If you have a "warm" surround, what's R=G=B will read blueish, and if you have a "cool" surround, it will read yellowish. So once the product render is put in an environment and lit by it equation of Neutral will immediately breakdown and product colors will read wrong. Because we read images, not color-pick them. Think about the blue-yellow dress debacle. I'd provide examples to this but can't attach images here ofc. Khronos Neutral makes your images look like renders in short. In my experience client isn't always happy with that, most don't color-pick their IP Hex values. If you load up an "hdri" with clouds and the sun and view it through Khronos Neutral you will immediately see what reads wrong, polarity flips and decrements galore. I think it takes the artist a couple steps away from the right track.
