Is it possible to use Curves to control band number/smoothness/offset the shadow with this setup?

I think HSV and HSL etc are different colour models which represent colour differently, just similar

so this is what its based on

you sound italian as hell... fire video.....

1:20 Maybe you weren’t serious in this section, but I’ll still mention it here for people who don’t know it: A sample is called that because a texture’s elements (shortened to texels) are sampled. Just like you can sample a function at discrete points and display the results in a graph. (Textures don’t store samples.)

my head hurts but im thankful for this tut

How do you get rid of the jittering? My outline is also very aliased.

Bicubic must be standard for games

This was a great video!! It taught me a lot, but I'm having a little bit of a problem. When the Kernel pixel is near 3 different depths (Like 3 objects at different distances, and the Kernel pixel is on the middle one) the line doesn't fill in. I believe this is because the Laplacian Filter adds all the depths together, and since the back object is far it causes it to not draw the pixel, but it should because it's on the edge of the closest object. I can see it a little bit of this happening on your project but on mine it's very visible. Do you have a workaround for this? I should add that the reason it's more visible on mine is because I changed the code to fix an issue with the Normal filter doubling up with the Depth filter on overlapping objects. I fixed it in a very weird way though so if you got any tips for that too that would be awesome :D

So I implemented this whole thing following this video, unfortunately in the game, specially the outline part, looks pretty bad, specially around folliage. The light division part, really is better than the alternative you picked up(prismatica one, which I also Implemented here), but I feel we loose the "artistic" ability to explode lighter shades vs darker ones. It does look pretty good on landscapes, accentuating the landscape geometry.

A true goldmine of a video, addresses every headache I've ever had with PP shading nonsense. Seems like understanding the tonemapper really unlocked it all for you. Thank you very much for sharing!

Really nice tutorial, I was going through this one again, and I'm not certain what texture is used for roughness? Is it a simple color or is there any patterns? I only see light blue

Through the conversation between the two of you, I was grateful to receive excellent advice on how to proceed with unreal lighting through experience.

有人在吗 我的卡信息添加不上买不了这个 谁能帮帮我

怎么添加卡信息 为什么我总是添加不上

This video was extremely helpful to me. I don't use Unreal but I implemented something similar through Blender's compositior, and it works really well! It's the low-maintenance accurate toon shader I've been searching out for years!

Wow, I'm blown away. Great video, Gonna take a while for me to digest all the info. But I'm going to have have fun playing with the new knowledge once it settles.

9 times out of 10 if the video is barely 10 minutes ill skip it over as a garbage tutorial unless i already know the channel such as this one. Nobody these days puts out useful tutorials, they all just copy eachother so they can get some quick and easy content out which in my opinion is why there are so many incorrect tutorials.

Came for the physically accurate cel shading tut, but was stoked to finally learn how to achieve a LOG output from Unreal!! This is huge, thank you. I can now use this post process to send production renders to colorists and let them grade it. Been wondering about this forever, I knew it was somewhere in there. Amazing.

This is amazing and incredible helpful! I was wondering how would it be possible to implement something like SSS to this stylized Cel shader? It's hard to find info on how to create stylized shaders while still having SSS work.

It is so wild seeing someone who really understands what theyre doing in multiple areas bring all that information together to nail down exactly what theyre looking for. This makes every other solution feel like its just faking it. Every time I start to think I know what I'm doing some wizard comes along and just does some crazy voodoo magic and blows me away. Awesome stuff.

Just an incredible tutorial. I love you.

0:24 agree games do look all a bit the same well really different game engines have different graphics but games of the same game engine just look very similar especialy ROBLOX (yes i know ROBLOX is a cloud gamimg platform but it kindof is a game engine) games even comparing crossroads to adopt me to dig to china to blox fruits (formaly known as blox piece) to blox tales to TDtNTOR to TDtNTOR 2 to TDtNTOR 3 to jailbreak to meep city to epic minigames to madcity to blah blah blah they all look very similar the most similar of any game engine

Easily the best video on this topic for Unreal that I've seen. I do have a couple of questions though; 1. Is there a way to control the amount of light banding? I've tried playing around with the numbers associated with the V channel but all I can manage is to alter the contrast and intensity of the banding. 2. Is there a way to get emissive materials to work with this post process? With this setup it looks like the emissive channel is completely ignored

Looks great honestly

I was really hoping you'd come out with a method for reducing the line's thickness based on distance, so this was great. There's only one problem now: a given object's line thickness will change based on what is visible behind that object and how far away it is. With that one wrinkle gone, it'll probably be perfect.

Do you have any workflows/lumen settings to reduce lumen artifacts. I'm getting very wobbly/fuzzy shadows

9:43 Do you know how to match EV100 values in 5.4? They've been replaced with "Min/Max Brightness" and the values don't seem to match 1:1.

Banging.

Note for 5.4 users doing this now - the post process material at the time of this video was supposed to be set to Before the Tonemapper, however this option was removed in favor of several new ones. Using Scene Color After DOF produces visually similar result.

As I understand, your outline works outside the mesh, which means I can't apply stencil check to not render it let's say if model is half in water. Any advice? UPD. Also, with this approach, I can exclude object that I don't want to use with shader :( correct me if I am wrong, but I can't see workaround here

i really love all your videos and the mathematical approach! :-) But to be honest, i allways miss the "shader complexity graph". Anyways, grazie mille!

Does it work on mobile?

Great video looking forward to part 2 :D

yeah baby this is what i've been waiting for

How did you make the material at 14:28?

Firstly, THANK YOU for this amazing breakdown. I'll def watch the rest of your videos as well and come back to this one once more haha. I have a question, do you think there is a way with this approach to control the look of individual bands on the shadows? for instance making the transition have some texture, or a specific tint of color on one of the bands.

Are you a fookin robot??? Im about as good as you can get at unreal in the scope of still only human ...but your obviously nerdamatron robot...

When I was in university I struggled for years (literal years) to try and make a toon shader in Unreal. Eventually I just gave up as the resources available and my own capabilities made me feel like I'd wasted a not insignificant part of my life. It's too late for me, but thank you so much for providing something so that the next batch of bright eyed kids don't give up on NPR.

I learned so much! Thank you for making this!

I'm glad they finally caught up to some of the other softwares that already have this. I guess everyone's leapfrogging everyone else.

great work thanks !!

Hey man love the video, regarding the outline, you could also use the inverted hull method. This would yield a more defined and darker outline that (as far as i understand) doesnt compromise our lighting integrity. Would you agree with that or am I missing something?

If I just want to use this 21:06 as my cel shader is there a way to make hdr backdrops work because mine is just black

How would you make the outline wiggle as if it was hand drawn each frame?

35:37 I think you invented image sharpening

You singlehandedly saved thousands of indie devs... This is astounding!

Man this is a gem!

you should do a kuwahara filter video! ive been really wanting to try it but i have no idea what im doing

Can this be replicated on UE4?
