“Hey Gaben, this edible ain’t sh-“

3:41 No matter how often it comes up, it still cracks me up that basically every Valve game is a mod of Half Life 2.

Other Games: Nooo! You can't delete that empty txt file! Chad TF2: You can delete %70 of the game.

>deletes 70% of the game files "for some reason animations are now incredibly broken"

"We buffed the medic by making the game crash everytime you kill one"

"Did you notice that? The wrangler laser IS STILL BLUE, OooOoOoOOoh. It has no textures, that damned laser IS the pinnacle of source spaghetti." - Lazy Purple, probably

So long as we have different step sounds, actual player models, Cow.png, and the blurry picture of HL2, we have tf2. Glad to know this game could survive a nuke and still make more sense than it does in it current state.

Broke: "Deleting this coconut crashes the game." Woke: "Deleting 2fort Cow crashes the game."

I like how it went from "tf2 can't run without the coconut" into "tf2 can't run without the COW"

4:56 surfaceprops also determines how slippery a surface is, so you will slide around on ice. It makes sense for the game to refuse to load if it doesn't know how you're supposed to move imo

Broke: "deleting a coconut will make the game unplayable" Woke: "Deleting footstep sounds will make the game unplayable"

Undeniable proof that Medic is the most powerful class in TF2

It says a lot about Valve's map design that even when the game is a textureless mess of pink and black, you can still identify maps and their segments perfectly.

The reason that some assets "fall back" to a hl2 asset is because they have the same name. It's why when you load tf2 maps in gmod the textures will sometimes look wrong.

The distortion effect without the texture genuinely looks really cool. Like an earthbound battle background.

Finally, no more lag.

"killing the medic crashes the game" looks like _SOMEONE_ at valve was too lazy to model a court scene for violating the geneva convention.

This reminds me of a mod I made for myself a long time ago. I was playing TF2 on a horribly outdated computer so I personally reduced all of the textures in the game down to a single pixel and I even got low-poly models of each of the games characters and weapons, so every object in the environment was a single flat color not unlike this.

Man someone should make like a challenge out of this, load into a causal server and every kill you get a file back.

7:09 "for some reason, animations are now incredible broken" TOTAL MYSTERY TO WHY THAT HAPPENED

"Killing medic immediately crushes the game" I bet you could hear him scream: "ai aaam a god!"

"A programmer decided to draw the line there" More likely the programmer never thought someone would start deleting files and didn't think it was nesseary to put in a check/fallback

5:01 Counter Strike uses this same system which accounts for bullet penetration through surfaces. A wood material vs a metal material is the difference between concealment and cover. It also decides what impact and bullet marks get applied to the surface. My guess is because this is critical to gameplay in other games it just carried over as essential here, too.

Comp players be like: "I can squeeze more FPS"

This is an excellent guide for FPS boosting. I have reached 38,595 FPS and causality warps around me. I have -30 ping, because my game state can be described in three bits.

No idea if this was mentionned, but the reason why the sky was smearing is because the camera in-game doesn't clear the GPU's frame buffer. Since there is a skybox, it would technically be cleared by being fully overwritten every frame, but with no skybox, any pixel without stuff to render (like the sky) will get the data from the last frame.

0:40 “You should be able to recognise where you are” Me, having been recommended this video despite no prior playtime of the game: Yes

TF2 Character and level design is so good that even with no textus it looks very playable. Team colours and particle effects would be nice though.

in grand Source Spaghetti fashion, the world hinges on footstep sounds, a random crank, the 2fort cow and locally robot sourced cash. also as a representative of the medic mains, we greatly appreciate the buff of crashing other people's games upon getting killed

5:52 scout forgot to instal Counter-Strike: Source

I would imagine the need for surface properties comes from some surfaces being more slippery than others. This would affect the game's physics simulation, like the movement of players and certain projectiles like grenades. TF2 relies on clientside and serverside sims being in sync, in order to function as a multiplayer game. So if the clientside sim doesn't know how to handle surface interactions, it's going to end up out of sync with any server it connects to. I imagine the check that aborts the game exists explicitly to prevent this from happening.

Ah, yes. The true Garry's Mod experience.

8:47 Missed opportunity for this to also be untextured

Tf2 comp players are salivating at this "Why yes I did make my game look like absolute dogshit for the sake of a 5 FPS increase"

surfaceproperties isn't only about footsteps, it also tells the physics engine how objects should interact with each other, for example it sets the friction of materials. Not sure why they decided to not just have a default settings for when there's no file though. Still, it's more important than you think.

"hello guys today i'lll show you my comp fps config"

8:00 " I'm keeping my eye on ya! "

7:08 "For some reason, animations are now incredibly broken." Yeah, couldn't imagine why.. Also, the red "ERROR" bits are fucking terrifying when paired with the textureless character models, good god

Fun tiny story time: i cleared cache of TF2 and then i found that the cache clear removed the eye texture. Now everyone stares at me with purple eyes

It's worth noting, when an error occurs because something is missing, it's not that a programmer explicitly decided the game should crash without it, such as the surface properties. In fact it's closer to the opposite, the game does not consider those files might not be there and there is no code to handle that scenario, hence the fatal error occurs. The rest of the files it will search for, but it has code to handle what to do if it doesn't find them, ie the purple and black checker texture. In other words, the programmers wrote code to allow the game to continue without some assets like sound and textures, but did not consider certain other assets might be missing. Errors, especially fatal, nearly always exist because there is no code to handle a scenario because it was unexpected.

The Gas Passer now has a reason to exist. If your opponent is playing without any textures it can distort their view, giving you an advantage in this extremely unlikely, extremely specific scenario.

The wrangler sphere being a solid ball is the funniest thing to me

The shading Is the big thing that makes things playable

The cow is basically a god that keeps the tf2 universe stable

2:40 bruv thats some good kush he’s smokin

The jarate effect is so interesting to me. The game must use a shader that picks up screen distortion values from a carefully designed texture. So it gets that weird square bubble look from the checkerboard

3:13 Update: sniper now uses a kaleidoscope as a scope.

Someone need to host a tournament like this with everyone having really high ping and using the crappiest hardware they can find lmao

The sniper scope is so funny lol. This is what game designers have to deal with when they playtest their game graphics.

That crank is actually a valve in one of the maps so a valve coder had some elite sense of humor and irony

Developer commentary: (guy with british accent) During early playtests people would often comment that while the game was playable, it was hard to know what was going on all the time. Furthermore, new players would also sometimes complain that while the models of the characters and core gameplay was interesting, it felt like something was missing visually. As a result, we added textures, player animations and other resources to the game. The end result helped guide new players, and had the unintentional side effect of being visually appealing.

He turned the sniper scope into a kaleidoscope. Funniest shit I've ever seen.

2:46 it looks like as if you are getting attacked by like a psychic attack would be a interesting flash bang kinda effect if it didn't make you wanna vomit

This is a fun idea, I wish there were some more videos on other games like this. It’s like taking it apart

Watch this turn into an aesthetic in less than 5 years. Errorwave.

tf2 still breaks even in its stable form

For those who are asking how many GB would TF2 have after this, someone here already gave an answer, but I want to add a fun tidbit to this: Nowadays TF2 is around 23-24 GB (more or less), however, I distinctly remember its size back when I started playing in 2014, which was 8GB (and it already took me quite a long time to download it). So basically, TF2 has doubled its size and then some in the last 8 years. Maybe its time to look for those extra cosmetics' models and put them in timeout.

Surface properties is probably one of the anti cheat protected files, it makes sense it should try to fetch and verify integrity every time the game loads otherwise you could change the characteristics of footfalls to never fall off or be extremely pronounced.

Comp players be like:

"the cow keeps tf2 from falling apart" sounds about right

I feel like I'm watching the game scream out in agony in real time.

This escalated from "TF2 can't run without the coconut" to "TF2 can't run without the cow" too quickly. And I don't have an idea why I even watched it lol.

This smearing effect happens because if there is no skybox or model to render it doesn't render anything at all and keeps the previously rendered pixels without overriding them because there is no default skybox Edit: the skybox is not really a model its just 6 images for every map that form a cube for every pixel that isn't overridden it renders the skybox

Heavy : "Now doctor!" **Proceed to turned into a fly**

love it when sniper scope turns into a kaleidoscope

This really showcases the quality in desing when the game is almest cometively playable without textures and also the messiness of the code when it crashes withot a cow on a random map

Shounic: Deletes all textures and almost all sounds from the game Developer: Shounic: Deletes footsteps Developer: So you have chosen... Death.

finally, boneless tf2

Very usefull info will use thanks for the tutorial

I would kinda love a community map to be made entirely of missing textures including both teams. Also that missing texture distortion effect looks kinda sick.

Average comp player config

5:09 I know why. Someone a long time ago exploited everything you're doing. Someone made every texture except the floor transparent to essentially have undetectable wall hacks to see through them. Well that's when they added the VPK update. That stopped that exploit. Now the foot sound effects was cause Someone could make Someone else's footsteps louder cause it USED to be separated in 2 separate wav files one for your own and another for the enemy nearby. Well that same guy made the footsteps earrape material and well...knew where everyone was by sound. So once the VPK update came out it solved THAT problem.... now they got more

"Did you maximize preformance?" Yes... "What did it cost?" Everything...

The distortion effect with textures looks awesome

Crazy how good designed the mercenaries are. Without textures you can clearly tell one from another still.

"If you kill the medic, the game will crash" can't even violate the Geneva convention in video games, cancel culture has gone too far

I love how he discusses the topic in a way like anybody in their right mind would go so far as to delete all of the sounds or textures to play tf2 in this state

I remember that one time when my pc was too bad that i had to manually optimize the game at the time i could see invisible spies and it helped me a lot to this day im still destroying tf2 just to encounter that file that made me able to see invisible spys

forgot to download css be like:

The most important question: what is the game size after cutting everything out and how much RAM it consumes?

KZfaq video compression has gone through all rings of hell to make this video playable

The game without the coconut: nothing The game without the cow: Unfixable chaos

5:43 I've never played the game but I do know a lot about 3D computer graphics and game development, so here's the technical explanation on why this happens. This is caused because the engine is not clearing the backbuffer before rendering to it, and it's also most likely doing a postprocess effect (likely bloom or dof) since there's nothing on the screen covering that area, the engine never renders any data so it just takes the previous frame and copies it until there is data.

Some of the information I've noticed in this video are fairly inaccurate. One primary thing that stuck out to me was the mention of removing the base VPKs causing the skybox to become the cascade effect. The reason for this is because textures use two files: VMTs and VTFs. VMTs are stored inside those base VPKs (with the models and particles), while VTFs are stored within the texture VPKs, so that's why they don't break when you delete just your textures, because the game is still searching for the VMTs, that dictate phong, bumpmaps, reflectivity, transparency, and looking for a texture to use; If it doesn't have a texture to use, it defaults to the error purple and black texture, which is why the skybox is relatively unchanged when you delete just the VTFs VPK. As for glass, the same principle applies, it's grabbing the error texture to use as a transparent texture, which... the error texture doesn't have an alpha mask to determine how opaque or transparent it is. Once you delete the VMT, then (afaik) the map handles it's transparency on compile, so loading a map without the needed VMTs doesn't apply the specifics of what those VMTs are meant to show. Heck, during the part before you removed the HL2 VPKs, the glass was still "functionally transparent", so HL2 had nothing to do with fixing the glass. Also, one last thing. I think the game crashes with the surfaceprops.txt due to the fact that file determines physics, in terms of friction, it's properties with waters, sounds, and etc.

I wanna see a gamemode where the sniper scope texture is removed and everyone is forced to use the machina

I’ve never played the game so I think it’s great the video was made in a way that’s accessible to people without prior TF2 knowledge

0:26 That's the same error pattern used in Minecraft.

shounic: *hits medic* Medic: "YOU DARE OPPOSE ME MORTAL?"

I just love how recognizable TF2 maps are even without any textures whatsoever. It goes to show that map makers really did a good job.

7:14 thought said “minecraft casual servers”

It was worth the wait gabe

This is like, TF2 on a MASSIVE budget

After the magic coconut... The holy cow And the crashing medic

thanks for this, I might remove some tf2 sound files because I prefer the hl2 sounds.

I'd imagine that surface properties or something else in misc 0 has something to do with map geometry as a whole, not just sounds.

Finally, I now know what my teammates see whenever I play medic

Medic and a Cow are the two pillars that support TF2…

Take this with a grain of salt is this is merely from my own experience and thought process with no proof attached. And do keep in mind that I personally don't play TF2 myself. I believe that you may be correct about some of the required files, but you may also not be. There are multiple reasons as to why the game would crash if a certain file is deleted. In the case of the VPK files mentioned in the video (0, 1 and 5) I do believe that it may not be as simple as "drawing the line" as in, someone decided that without this random unimportant file you could not keep going, but rather that some file or line of code requires this file to give specific information and if it can't then it crashes due to not knowing what to do. It's the same case for many programs as well as Windows in that matter. There are a lot of essential files Windows allows you to delete and that aren't important, but if you were to launch the operating system, it would not launch due to another piece of code not knowing what to do. It's a failsafe mechanism. If something goes wrong, it crashes. Though you may be correct, I believe in this case this could be the cause as I feel it is improbable that some person has decided that "that's enough" on a random file that would otherwise not do anything, however still possible. I believe that if another file or part of code is deleted that could cause this crash, you may be able to delete it and continue (talking about specifically file VPK 0 here) however it would take a lot of work and don't believe it to be worth the effort for just one more deleted file. Great video though! I love the editing and hope that you continue to do more content like this!

surface properties might be that the game WANTS to be able to play all sounds, even if they aren't there to be played, so the game crashes when the file to check to play the walking sounds is missing, potentially from the missing file causing code that previously called on it to break
