I made a Minecraft map that is IMPOSSIBLE to SCREENSHOT

[@DqwertyC]

An issue with the shader that caused the entire screen to be black with some graphics cards has been brought to my attention. Thanks to some super sleuths on Discord, we were able to find and resolve the cause of this issue. As of the time of this comment, the world download on Planet Minecraft has been fixed. Another issue that caused players to start in Creative mode (even though the default gamemode was set to adventure) has also been fixed

[@GemStar4071]

i played the world myself and it happened to me too, i then later set my brightness to 8000 and it worked like normal

STATICNOISE

[@poopalachas]

I was wondering if it could be changed to only shift when something is moving

[@DqwertyC]

@poopalachas That should be doable! Basically, instead of having different layers moving at different speeds, they'd just have different patterns of noise. You'd be able to see the boundary between the patterns as it moves, but not otherwise

[@adicsbtw]

It seems like the shader sometimes starts to flicker for me, rather than just shifting the noise Edit: after beating the map I went back to test, and it seems like the flickering happens at low framerates, so I'm not sure what can be done about it. I just disabled vsync (apparently I forgot to do that before) and that fixed it for the most part

[@PendragonDaGreat]

I'm honestly amazed at how well youtube is handling so much noise on screen without the compression just freaking out.

[@Maplaplaplapla]

I was wondering why the noise seems like a repeating pattern. Now I realised it's the compression trying its hardest. I think most of the other strange artefacts (for example how if you pause, it's not clean noise but has some evident boundary areas) are also from compression. A coarser noise resolution might work better on video

[@wChris_]

Its because most of the noise is static. And the part of the noise that is moving, is moving in a predictable way.If you were to randomly change the color instead of moving the pixels, than youtube would crap itself with compression artifacts.

[@dinhero21]

vp9 doing its magic

[@haph2087]

@@Maplaplaplapla The core goal of this method of video which disappears when paused was to *not* break the compression, because prior naive approaches did, and it broke the illusion.

[@YoutubePizzer]

it’s because with pure noise, every pixel changes every frame, which is a lot of data. Here only some parts shift in a unified direction. Compression algorithms work similar to how our brains see, so if the picture isn’t busy, the video compresses better

"clearly" is a bit of a stretch xd

[@stefanbergung5514]

You have all noise moving down. This makes an environment difficult to make out. Hove horizontal surfaces move the noise downward on your screen, while north/south pointing makes noise move right and west/east surfaces make noise move left.

[@DqwertyC]

That might work! I'm not sure how I would go about extracting that sort of information from the values I have access to in a shader, though

[@埊]

@@DqwertyC an idea: at the end of the map put some boss fight

[@arlo314]

@@DqwertyC I may be wrong but wouldn't you just need the face normals for this?

[@raspberryjam]

@@DqwertyC calculate some rough normals by projecting vec3(screen_x, screen_y, 1.0) times float LinearizeDepth(float depth) {return 100./(1000.1-(depth*2.-1.)*999.9);}, with depth from DiffuseDepthSampler and TranslucentDepthSampler. Sample projected points for the current pixel, one to the left/right, and one to the top/bottom. norm(cross(norm(left-cent), norm(up-cent))) is your guy. I made a slightly jank skulk shader so I have this information on hand

[@KindOfWitch]

@@DqwertyC surfacenormal of the surface constrained to 2d is the direction you move if?

[@mistyntoby1593]

Bet. If you want to screenshot it, you have to take a picture of the movement. Now, obviously you cant do that because the noise is moving down and you cant make out an environment. However, you can stack two of the same videos together and have both at 50% opacity, with one inverted and slightly ahead of the other video by a few frames, and you can get an effect that lets you screenshot. You may need to add a filter to see it better, but it’s all possible in even the simpler video editing software, like CapCut.

[@HarrisonMartinson]

If you want a really clean and simple way to do it, save 2 frames that occur right next to each other. Load them up in Gimp as 2 layers and set the top one's layer mode to Difference. The background will now be solid black. By the way, on the browser version of youtube you can right click the video twice to get a copy/save frame option.

[@alwaysnoita]

just remove the shader bro

[@LilCalebW]

​@alwaysnoita that ruins the fun

[@egornick9206]

My video lagged the way moving parts just became blurred, so I was able to take a screenshot Thanks, router

[@drawerganizer785]

I'm impressed you can do that with just a resource pack. Only piece if criticism is that the noise is a repeating pattern so you can still make out some edges when it's paused from breaks in the pattern.

[@DqwertyC]

That's more from KZbin's compression algorithm than the datapack - there might be some repeating in the noise eventually, but it uses a (admittedly really dumb) perlin noise generator with a large enough range that it shouldn't repeat on most screens

[@apia46]

idea for the qr code: take two screenshots, then compare the difference

[@Yellowsam4145]

Yea that's it.

[@mahdoosh1907]

[@hamzamotara4304]

I had a much stupider idea. Write the QR code down while the game is unpaused XD

[@fdagpigj]

I haven't tried the map but why not just like... scan the QR code with a different device?

[@zausenecz]

[@jucanavazreque3429]

I was following that series as well, had to click on this video as soon as I saw the thumbnail XD Looks really interesting! I'm wondering what's the criteria to make the shift go upwards or downwards...

[@DqwertyC]

Colored pixels on transparent blocks shift upward. Solid blocks are mostly static, but by setting pixels in the block's texture to be semi-transparent, those pixels will shift downwards. Entities and most UI elements shift randomly, providing a more traditional 'static' effect

[@professorvatcraft]

This is actually a simple yet interesting concept :O Too bad youtube compression is not doing this justice.

[@missiletechradar]

"just use recording software to record you playing the map and screenshot any frame you want" is what i thought, but im stupid asf

[@greenstonegecko]

Bwahahahahaha!!! Amazing. Just looking at this for 4 minutes is straining my eyes xD You should do a minecraft speedrun with this shader!

[@szyl]

I can clearly see that this is a pretty neat project clearly

[@gribblegrape6496]

This mod is the equivalent of your friend who doesn’t was their hands after eating Cheetos trying to show you a meme on their greasy phone screen. Lmao

[@TheStealthyOne6]

this is a really cool development, i was wondering when people would start to make games on this. This would work best if there were certain static blocks (working similar to the End Portal blocks in that there is one static pattern no matter where you are) and a solid floor, and you could only see an entity in this way. Other than that, the entity is invisible.

[@RaPsCaLLioN1138]

I saw that series as well. Very cool to see applied to MC.

[@mooing_cowmilk]

possible to have a separate download for just the resource pack?

[@DqwertyC]

I've added a secondary download link on Planet Minecraft that has just the resource pack!

[@Boooo]

Something cool about this affect on youtube that I just figured out is that if you move forward one frame while paused you can see the next frame "clearly" for a split second before it goes back to just being a bunch of noise, it's kind of obvious that this would happen but I just find it neat.

[@utkanbaskadem7904]

This is so cool! Great video, thanks for making this :)

[@peglin5117]

I wonder if it’s possible to indicate color with the noise. Maybe it could use colored noise shifted by each blocks’ pixel hue

[@DqwertyC]

I did try something like this in the early testing - angle of noise was determined by hue, and speed was determined by whatever the V means in HSV. It was a bit of a mess with anything more complicated, but worked fairly well in a world that only had concrete and wool blocks

[@jackatk]

Wouldn’t that just ruin the effect?

[@StarkmanGG]

Really cool effect!

[@ZephyrysBaum]

Your resource pack is sooo cool! Didn't know you could do that! Tried it on different worlds and servers

[@Golem642]

Maybe you could have a setting to accentuate the effect and allow for more render distance ? It might hurt the eyes a bit too much tho lol

[@DqwertyC]

There's a reason the entire map is in an enclosed space... With regular terrain generation, the effect will ignore fog, so the render distance is whatever the players settings are

[@danielknourek]

Nice work! Could be interensting to make some tools to just add unscreenshotable paintings or some other dispaly tech, and in a normal map you would stumble upon this display you would need to remember bc you could not screenshot it!

[@SubGplayz]

Thats so cool! How do you think it would look if the shift speed was dependant on the brightness of the pixel? I think it could make seeing details better

[@dovos8572]

it works better if you don't change the picels back to the background noise pattern but leave them as the last frame was and only change the pixels that move. that way you have a noise background that doesn't repeat and it changes over time.

[@ThatNerdGuy0]

"yo guys i found this map but im struggling on it, can you help?" "send a screenshot"

[@anastasiaklyuch2746]

I feel like this is what it looks like when you are almost blind but can still get SOME visual information. Or when you're blind and need to navigate by noise. Wow.

[@Epicdoge1091]

I love that this has become a trend Pretty soon, someone's gonna do bad apple and doom with this idea

[@corruptconverter2616]

Thanks to KZbin compression, some details can be made out when paused.

[@GameJam230]

I used this same concept to make a little demo 3D space in GameMaker after I first saw some videos like this a few years ago. Was planning to make some sort of horror game out of it, but never bothered to continue

[@jacoblockwood4034]

Very cool! I couldn't get the resource pack to work though, I just played the map without it lol

[@FlooferLand]

Trying to scrub through the video is so funny, the frame preview thing that shows up when hovering over the video progress bar is just noise

[@darth_dan8886]

I'm sure KZbin compression had a field day with this one. "This is clearly a beacon" got me laughing so hard as I was trying to parse what that vague shape on the screen was supposed to be XD

[@DqwertyC]

Yeah, in retrospect that was a bit too confident on my part :P It is clearer in full screen at 1080p, and much clearer actually in game

[@Idknlandwh123]

[@butlazgazempropan-butan11k87]

"screenshot this, you filthy casual!"

[@oliverdowning1543]

Would be interesting to have 3 overlapping noise patterns in each or red, green and blue so that they could change the speed at which they refresh (move) in order to depict colour.

[@Epicdoge1091]

Somehow, the bitrate wasn't awful, but my eyes were heavily confused, and I kept getting these "surreal" moments, although I don't think that's the right word.

[@Excalibur_Fusion]

I'm glad that someone thought to put this concept in minecraft! Great work

[@jayyusi]

I remember playing a game on itch that used this effect for the whole game, it was fun.

[@danatronics9039]

I wonder if you could get distinguishable colors that can't be screenshotted by using a certain pattern of colored pixels in the noise and only moving pixels of different colors for different objects? That would probably require different "layers" for each color, though, and I'm not sure whether shaders can do that.

[@4sent4]

I like how actually figuring out the qr code gives you a completely different result than just disabling the resource pack

[@DqwertyC]

Shhh...

[@MustacheManBoyHairyManChild]

i really dont know if this would be possible but maybe using different colors would make it easier to read whats happening

[@olillin]

I had a similar idea after seeing that some video, nicely done!

[@jackatk]

In some places I could definitely still see the image when the video was paused…. I think this may be because the original brightness of each pixel is somehow factored into the noise? But this is really cool anyways!

[@kitlith]

It's probably video compression artifacts. Areas that haven't changed for multiple frames are more likely to be fully detailed than areas that are changing.

[@jackatk]

@ I saw another video on the same concept a couple weeks ago and it didn’t have the problem tho

[@NoNameIdk1]

[@lucashoffses9019]

Sometimes when I pause the video, I can still see the grid outlines of the wall

[@DqwertyC]

Yeah, that has to do with KZbin's compression trying to find patterns in the nose to make the file smaller. Those artifacts aren't there in the resource pack

[@olegmoki]

I've got an idea of screenshoting: doing a photo with longer exposure

[@DqwertyC]

That could work! The only reason humans can 'see' things with persistence-of-vision is that our eyes effectively have an exposure time longer than 1 frame. (This is an oversimplification, but it's similar principles)

[@tormentedterror]

That's what we need

[@what42pizza]

Are you using the pixel coordinates and time as the input for a hashing function? If so (or if it's something similar), is there any particular reason why you don't have larger pixels?

[@DqwertyC]

It basically has to do with the order different layers are rendered to the screen. With larger pixels, there's no way that I've found to avoid partial pixels along the diagonals between different shader passes (so along the horizon there'd be a noticeable region of shorter pixels, for example). You can get larger pixels by putting your game in fullscreen but reducing the 'fullscreen resolution' setting to something smaller than your actual monitor

But basically, I guess it needs to be some kind of constantly changing encryption, and if someone manage to break through the encryption they still only see noise from one frame, and would need several more frames to compare against to be able to find the pattern?
