The coolest shader effect that nobody uses

So posterization is just so insanely cool and for some reason it's very underused in the gamedev industry. In this video I explain how posterization can be used in some unconventional ways to generate some incredible effects, and even custom color palettes at the end.

Use a low resolution, add a dither matrix, then do the posterization and you can call it "pixel art".

[@Beatsbasteln]

fun fact, if you apply the same term "y = round(x * a) / a" to an audio signal, with x being the audio signal and a being the parameter, it becomes what is typically known as a bitcrusher effect

[@xenontesla122]

Yup! I’ve used this effect both visually *and* sonically to make music that generates animations when put through an oscilloscope

[@iamsushi1056]

That’s true smooth bitcrushing. True bitcrushing has an equal to a power of 2. (Ironically, using the same formula on the time scale produces the similar effect downsampling, which is often misconstrued or falsely marketed as “smooth bitcrush”)

To get optimal (most similar to the original) posterization the OkLAB (OkLCH) should be used. This is a colorspace designed to be perceptually uniform, which means that if you split your colors in equal intervals neighboring blocks would look equally similar/dissimilar to each other. Edit: pasteurization -> posterization

I'll look into it thank you for sharing that!

Ok lab is super cool and I was wondering if you had seen it or not guess that answers that question

[@AlessaBaker]

It was briefly mentioned that this can be used for accessibility features, I would assume here you meant CVD support (Color Vision Difficiency). In general, filters that shift total screen pixels are filters to assist those who aren't vision impaired to see what we see. However, in practice, it is actually better to _only_ change the colors of things that are important - Pickups, enemy colors, etc. Unfortunately, the only real reason filters end up being the norm is largely because Accessibility is an after-thought. It becomes a lot easier when you set your base materials up to support this at the beginning of development. The reason for this is rather simple, but just because we are missing/mixing colors, doesn't mean we can't see bad ones. Purple skies, red grass, it becomes visually harder to see everything else in the game because we have to spend a lot more energy trying to interpret things we know the colors of, to the new palette. So the advice - Please only change colors, of things that are visually important to the player as gameplay relevant - not the rest of the screen. That's my little PSA.

[@nitro-gen-studios]

Yeah I have to look into how to properly implement accessibility stuff later. It was just a random thing I wanted to show. The real game (as shown in the multiple palettes part) gives different colors to the items and enemies which is probably good for accessibility but I have no clue honestly.

[@Aeduo]

Could be a useful option maybe for games with modding capabilities. It's a lot harder to expect amateurs who just don't know and just getting in to gamedev through modding to know to do this. It might make everything look bad/wrong, but if it can help to discern something _at all_ then it could still be useful in this case.

[@Theunjduvqhfurbsi1102]

Dude, using noise and posterization at the same time to create a shadowy effect is sick. Thanks for showing me. I'm totally using this for something in the near future. Also I think that there is a game called acid knife that I'm now positive uses some form of posterization.

[@WiseNoodleOfficial]

I think Lethal Company uses this effect for their style, I’m not certain

[@nitro-gen-studios]

Yes it does! If I remember correctly they posterize Unity's built in volumetric fog in some weird way.

[@Tetromiko]

Acerola in one of his videos, analyzed what filters are used in Lethal company

[@isheros]

A while ago I experimented with posterizstion by grabbing the closest color of an array, using the euclidean distanve formula. It worked well, allowing me to set custom palettes, but I think your approach will be more flexible and have better results. Looking forwards to future videos!

[@nitro-gen-studios]

I did something similar as well before I discovered that posterization exists! It can definitely work better in certain scenarios, but this solution is more flexible and can be adjusted in real time while having a set color palette can't.

[@davidtirado2330]

I personally use a mix of HSV fiddling and a sampler cube, I think it gives me more control over the color without letting me absolutely destroy the game's visuals by accident.

[@iamsushi1056]

I'd definitely look into the LAB color spaces (especially OKLAB) if you want to play around with posterizing more. LAB colorspaces, especially with posterization unevenly applied between the three color variables (different amounts for each, for example, or a different offset value (like phase shifting a sine wave, except it changes the points where the posterization starts instead)). It's one of the few that don't look too bad when unevenly posterized, in fact. There's also a set of sibling ofshoots, OKHSV and OKHSL that quantize nicely. But personally I like them better when only quantizing one or two of the variables.

[@nitro-gen-studios]

I'll look into those colorspaces soon!

[@lucidattf]

in some cases, also using dithering would make a better look. there’s a video in the “HTTP 203” youtube series about dithering, and a companion blog post, which could be interesting to you! I do think though that the banding not using dithering gets you is aesthetically pleasing sometimes, so maybe you’d wanna keep it as-is- just a thought :) great video!

[@nitro-gen-studios]

Yes I want to keep my game on the cleaner side, so I'm not going to use dithering as it can potentially look somewhat noisy.

[@basiliotornado]

That looks way better than i expected. Great technique

[@nitro-gen-studios]

Thank you!

[@Monody512]

As a video editor, posterization sets off my constant fear of visible banding from running into the limits of the 8-bit color space. :P

[@ghostlysander]

As a beginner pixel artist, I learned a lot from this video. I also didn't know of dark=more purple and light=more yellow, which... is a bit too simple for my taste, but it is still helpfull. Besides that, all the different posterizations will serve as inspirations for my color palettes

[@nitro-gen-studios]

Good luck with your pixel art journey!

[@Aeduo]

I imagine it's just a broad rule of thumb and not a "you must do this in all your art and it's wrong if you don't", but more an easy means to make something look more interesting and more "sunlit" than just changing brightness and no other parameter. Obviously different styles will call for different methods.

[@liz4133]

Such a cool video. I was playing with posterisation and wondering how I could make it better. Nice and concise video. ❤

[@WiseNoodleOfficial]

Very cool effect! I will definitely be using this in future games!

[@NickCombs]

I think the trick to making this effect look really nice is to ensure all of the banding goes along smooth curves rather than noisy edges.

[@nitro-gen-studios]

Completely depends on the artsyle you want. I wanted to make it look a bit less smooth but not as noisy as something like dithering.

[@NickCombs]

Yeah, that's a fair point. I do think a cleaner look is going to be a more popular style though.

[@wormcake_]

7:55 first games that come to mind are Lethal Company, Broken Reality, and ULTRAKILL (ultrakill's posterization is dependent on graphics settings and also has a custom color pallette feature)

[@RetroDead]

i absolutely love posterization, and its something i try to shove into my visuals whenever i can. was actually doing that while looking for something to watch

[@fa-pm5dr]

as a mathematician, i think that the distinction between color model and color space is absurd

[@foreign_objective2855]

imo posterization looks great in brighter visuals like daylight landscapes because there's more color and it's easier for the shader to pick it up. But for visuals that tend to be dark, especially in video games, I really hate it. In scenes that are very dark, even a small difference in value/tint of a certain area of the screen can change your perspective of the dark like "oh, there's something there" but when it's posterized, it gets locked in the closest color allowed by the effect, which makes things harder to look at. So basically, it's a cool shader but most people want to see more color.

[@Daemonworks]

You can find examples of posterization in mapping. Meteorological maps may posterize pressure or temperature regions as an overlay. Same with distribution maps. Topographical maps are basically a map with a z axis rendered via posterized steps. Enter the spiderverse also simulated animating at differen frame counts (on ones, twos, threes, etc) which is essentially posterizing motion to achieve the effect of accentuating miles initial clumsiness compared to the others.

[@nitro-gen-studios]

That's really cool!

[@lepsima]

I've looked many examples of posterization shaders this past month, each using a slight different approach, but the simplicity of converting HSV to posterize instead of RGB sounds so obvious, also perfectly explained

[@KazmirRunik]

You can get a similar effect on Web pages by playing with the filters in CSS. It's a superset of the CSS metaball effect, but you're also playing with other parameters like colors & filter areas of effect.

[@JayFolipurba]

Banding has its appeal, I personally prefer dithering

[@nitro-gen-studios]

Dithering can look noisy sometimes which is why I'm avoiding it here.

[@apersunthathasaridiculousl1890]

[@ScyrousFX]

It's used heavily in NieR Automata. The EMP attacks in route B (or C, I forgot) disable parts of your controls and introduce visual glitches. The posterization effect is one of those glitches. Very cool stuff.

[@sinom]

Posterization is really cool. Last yeah I wrote a really customizable reshade shader to do it. One thing I found really interesting was applying it to other buffere than just the color output. Posterizing the normal buffer, gbuffer etc. can give some really interesting results

[@wizard4599]

Hah, I actually did this today at work for a certain shader. Posterisation isn't just for end graphics, but can also be a great tool for generating masks or other elements that make up the final image. In my case, I used it to create a procedural grid texture by posterising the X and Y axes of a texuture coordinate.

[@nitro-gen-studios]

You're welcome! I have already seen that video when it released :D

[@Aeduo]

Oh I was recently experimenting with just this very idea. I was inspired by how original Doom's palette breaks up levels of depth in to different brightnesses to give the appearance of dark regions having lower detail where you can only maybe see some contours of objects and textures. I added a bit of randomness to the brightness channel per pixel to kinda fake temporal dithering while still keeping the effect of shadowy stuff being low detail and indistinct. Obviously would have to be used in a very stylized kind of game. I know lo-fi horror is kinda overdone but yeah it kinda matches this perfectly. :p

[@robbu2445]

Valefisk used a similar effect in his game crypt

[@nitro-gen-studios]

[@nitro-gen-studios]

[@vailias]

Generally speaking its much easer to get good quality visuals by just deciding on and creating a limited pallete, crisp edged art style, then apply a very simple lighting model rather than apply a quantization effect to one of the smooth lighting models and more "realistic" art. The control of the final scene part is a big part of why special effect shaders like this don't get used as much, since you have to design your assets with this look in mind anyway.

[@RoyceInsanity]

[@TheJamesM]

Personally once you leave the domain of colour I'd use the term "quantization" rather than "posterization", but the latter's Wikipedia page describes "time posterization" (reducing the effective framerate without changing the runtime of the video), so I guess there's precedence for the word being used more metaphorically. (The term originally derives from the appearance of posters printed using a limited colour palette, as is common with some methods of printing.)

[@nitro-gen-studios]

Yeah, I've seen a bunch of people call it "color quantization" when talking about color posterization, but I just didn't really want to confuse the viewers by using multiple words to describe basically the same technique.

[@TheJamesM]

@@nitro-gen-studios That makes sense

[@pokefreak2112]

Quite a few games use posterization. But it's often just one part of the effects chain because on its own it can be quite overbearing. Off the top of my head there's A short hike, fight knight, cult of the lamb (in the afterlife scenes)

[@nitro-gen-studios]

I'm pretty sure none of them do. Fight knight very obviously uses an unlit shader and bunch of texture work. A short hike probably uses some sort of simplified shader model, but most of it is also texture work. It's definitely not posterization because of how smooth the colors look at some places (especially on the fog). Idk what you mean by the afterlife scenes in cult of the lamb because I've never played it.

[@pokefreak2112]

​@@nitro-gen-studiosYeah I guess I misremembered about a short hike. It uses shading ramps which I guess is technically posterization but not what you meant. Not sure what you mean about fight knight though? If you look at gameplay you can see the colors pulse while the palette stays fixed. To me this very much looks like: sample black&white texture->oscillate brightness/contrast->posterize->sample palette

[@nitro-gen-studios]

@@pokefreak2112 I looked at some gameplay now (I only watched the trailer before). It does look similar to what I did, but keep in mind that you do not need posterization to sample a palette. I've done similar things before without posterization, but I can't really tell what exactly they used now. You'd need to use Nvidia Nsight to tell, but I don't have the game nor really want to spend time on trying to figure out how they did it.

[@Stoneeeeemo]

LOVE COLOR QUANTIZATION

[@jlewwis1995]

Imo for this type of effect in a game im frankly of the opinion it would probably be better just to use either specially made greyscale or red+green textures with a lookup table, an upshot to that version would be quite a bit better performance since you have to do less math, i guess the downside though is that it would take a bit longer to make the textures since you have to convert them to the right color format first which would involve mapping the pixel colors in the source image to UV offsets of their corresponding colors in the lookup table and idk if theres a pre existing tool that can do that...

[@nitro-gen-studios]

Simply put, no. Sampling a texture is way slower than doing a few simple (stuff that's not trig functions, sqrt, etc.) math operations. Also the palette generation pass is barely noticable in terms of framerate drop, if at all. The only noticable slowdown (0.33ms) is adding more palette layers, as rendering them into their seperate sub-viewport is quite inefficient, but currently there isn't a better way to do it without. Someone recommended the use of stencil buffers, Godot currently doesn't support it yet. Also the entire point of generating palettes in realtime is that you can change it in realtime. That is simply impossible to do the way I did it with a lookup table.

[@nitro-gen-studios]

You could probably make it work, but I'm trying to keep it all procedual.

[@Scruffysnake]

@@nitro-gen-studios yeah I was thinking keeping it procedual would allow for the effect to be changed real time, though I suspect a LUT would be faster (not that it matters with modern day hardware)

[@nitro-gen-studios]

@@Scruffysnake Sampling a texture is probably slower than this. Posterization is literally 1 multiplication, 1 division and 1 round function, but yeah it probably doesn't matter.

[@Scruffysnake]

@@nitro-gen-studios possibly yeah

[@markigames7313]

Isn't that a cell Shader, that is used frequently?

[@menaced.]

Kind of? cel shading is a material shader generally whereas posterization is a post process effect. Cel shading kind of uses posterization as a portion of it but it usually only uses 2 values (light and shadow) and the adds an outline afterwards

[@nitro-gen-studios]

@@menaced. Correct! I did add an outline shader in my game because combining the two effects looks really nice.

I heard you right! by the way, I really liked the video, it reminded me of the Acerola youtube channel.
