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 I was playing TF2 on a horribly outdated computer so I personally reduced all of the textures in the game down to a single pixel and I even got low-poly models of each of the games characters and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.
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.
@@LaserBread fatal errors are just errors that prevent the program from continuing. This results in the application exiting, or if it's lower level like a kernel operation, the computer will crash. Usually these errors are handled explicitly to end the application in order to prevent the application from simply freezing or to prevent memory leaks from destroying the program and creating undefined behaviour. Errors of this nature are especially bad with code running in the 0 ring (like kernel operations) since they do not have the same level of safety as regular sandboxed programs.
@@LaserBread Confidently incorrect? A fatal error, by definition, is an error that makes it impossible for the executor to continue autonomously. Also important is that an unhandled error is not inherently fatal. For example dividing by 0 in one environment might produce a fatal error since the executor has no resonable way of interpreting it, but in other environments a division by 0, while still an error, is not fatal (e.g. produces NaN instead of a number and then continues execution). However most environments _by convention_ (not necessity) will treat all unhandled errors as fatal, even if there is a resonable fallback.

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
To be fair, I'd wager there's probably more script-related files in the first misc .vpks that crash the game if missing like surface properties. I imagine surface properties is just what the game chokes on first. No idea about the other archive with the cow though, without an error message to go on I'd be pretty lost and I'm feeling too lazy to look through it myself.
I think you have all players on similair machines with limiting hard-disk space, rab, etc. and let them chose what to keep and what to delete for performance. Maybe you can render players and avoid mirror-skybox glitch but you run at 2 fps. Or you delete the playermodels (having to rely on cursor to determine teamates) to get your fps up to 8. Would be funny.
@@nwa8169 Not having all those files doesnt mean there are more errors and exceptions, it could actually be faster if not having those files result in early outs in otherwise computationally expensive functions.

@@nwa8169 I couldnt find anywhere in the video where you can see the console.

@@king_james_official a lot of maps need css because the creators used assets of the game in it, kind of annoying as I don't want to buy a game purely for another one
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
One question about that is in Fallout 4, when you see the sky without any rendered pixels there recently ( like the dev room) it starts black and then white holes tear through the black after you load in. Even if I wasn't looking around. It would start black. Then go to white, and have the smearing effect
@@federicohansen4561 The way Cubemaps work is kind of weird. They are just a cube(a model, perhaps) that is barely any bigger than the camera's fov. It's just some trickery so it appears as a giant box. Perhaps when you delete all the models, the Cubemap isn't rendered at all. This actually happens because the screen isn't being "cleared" for performance improvements (as in normal circumstances it would be useless because all pixels would be re drawn on) The effect of the screen going from black to white might be a shader thing, as some effects (particularly auto-exposure) might change the brightness of the rendered pixels depending on the current brightness of the screen. That is, the algorithm sees a dark image, so it increases the brightness over and over until it's very bright
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.
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
When I used to play cs_office on Garry's Mod without CS:S textures, I'd be able to see through almost every wall. Now I understand why that's permitted! It was made before anybody could abuse the wallhacks!
My theory is that the game needs to be able to tell other players in the server what surface another player is on through playing these sounds. If your copy of the game can’t tell what surface you’re on then this information can’t be relayed to other players.
@@theylivewesleep.5139 The surface properties file also handles how much friction to apply to players and other objects, so I think without that, it crashes not knowing how to resolve the math for that
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
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.
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.
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.
Mostly just means you played enough TF2 at some point to burn the maps into your memory, really. I'm like that with Runescape. Played for like a year or so when I was 10 and can do the OSRS geoguessr thing totally fine within a tile or two, which just feels insane, but it's just how things go. You gotta know maps to play the games well.
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
@Hoovy Simulator 2 the scope texture doesn't change anything for bots, they view the game through text, it's why they see right through disguises and cloak
@shounic A bit of a major correction here that I gotta point out There's a HUGE reason why surface properties cannot be deleted - the physics engine uses them for calculating mass If you think about it, a 1x1x1 meter block of concrete is going to weigh significantly more than a 1x1x1 block of Styrofoam right? In addition, the Styrofoam block is less dense and more airy. So, the physics programmers at Valve figured that they could use surface prop type as a quick way to auto estimate mass when compiling a model, with a default no material backup being used with a density and weight of 1. So by deleting the surface props.... you delete the custom densities and masses of objects and reset them to the default... which makes the physics bad.... So some quick foresight made it so that it just crashes the engine if there's no surface prop file. Oh, it's also used for creating bullet decals. Disclaimer: this is how it used to work (As far as I remember at least; it's been a long time) back in the old Source engine pre-Orange Box. I don't know if it was ever changed later, but I don't think it was.
Those animations at 7:29 are just incredibly cursed. Like when someone makes their first game or mod, and stuff technically works, but nothing has been animated yet.
5:09 "But a programmer just decided to draw the line there" I think it's much more likely that what happened was a programmer didn't think anyone was likely to delete that file, or the thought of deleting it never even occurred to them, so they didn't put in any error handling for that scenario.
Nah, there's an explicit requirement for that file to be present and unmodified, so that people don't edit footstep sounds and texture transparency. Cause that's an easy way to cheat.
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.
@@theotv5522 I’m pretty sure he’s just calling himself a superman. Valve confirmed long ago that Medic never worked for the Nazis at any point in his life.
this video shows how good the game design is,even after deleting game textures, you can play the game(exept the team colors),and also the sorce spagetti monster
The fact that these maps are so iconic that you can tell what they are based PURELY off of the geometry says something about how amazing the map design is.
"A programmer just decided to draw the line there"... more like the programmers wrote code that assumes those files exist, and they didn't worry about the case where the files are missing, because it's fair to assume players should have all the game files to play. It seems likely they could make the game work without surface properties files, but I don't see why they would be motivated to do that.
New maps introduce new textures all the time. Sometimes, these textures don't load properly. I wouldn't be able to play half the time if it weren't for that.
surface properties is more complex than just step sounds, it identifies, well, what type of surface is the player interacting with, like if its a liquid or not, if its breakable, how heavy the object is, how much friction applies, how dense it is, wich impact decal should be used, etc
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.
The fact that you can mod sounds files, makes it so you can mod the sound of spy's cloak to be a constantly playing sound, or much more drawn out than it was, to assist you in detecting them.
What I find really hilarious is the fact that, technically, TF2 is just a Half-Life 2 mod. It even uses hl2.exe to run xD Well, I guess it helped a lot to ship the game as a part of the Orange Box.
Technically when a game is built in unity for example, you could frame that game as being an "unity mod". At the end of the day, if you really want to make a program from scratch you must first invent the universe.
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
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.
This feels like when I first played Garry's mod on a crappy laptop. I have the achievement for getting 500 Lua errors because it just couldn't handle it, and when I did manage to play online, so much was purple and black, but it was still amazing

Errors, especially fatal, nearly always exist because there is no code to handle a scenario because it was unexpected.
In fact, fatal errors in programming do not exist. Unhandled errors are what become fatal.
@@LaserBread fatal errors are just errors that prevent the program from continuing. This results in the application exiting, or if it's lower level like a kernel operation, the computer will crash. Usually these errors are handled explicitly to end the application in order to prevent the application from simply freezing or to prevent memory leaks from destroying the program and creating undefined behaviour. Errors of this nature are especially bad with code running in the 0 ring (like kernel operations) since they do not have the same level of safety as regular sandboxed programs.
@@LaserBread Confidently incorrect? A fatal error, by definition, is an error that makes it impossible for the executor to continue autonomously. Also important is that an unhandled error is not inherently fatal. For example dividing by 0 in one environment might produce a fatal error since the executor has no resonable way of interpreting it, but in other environments a division by 0, while still an error, is not fatal (e.g. produces NaN instead of a number and then continues execution). However most environments _by convention_ (not necessity) will treat all unhandled errors as fatal, even if there is a resonable fallback.

Crazy how good designed the mercenaries are. Without textures you can clearly tell one from another still.
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
but the skybox is inside the map itslf. so, why is that .happening?
One question about that is in Fallout 4, when you see the sky without any rendered pixels there recently ( like the dev room) it starts black and then white holes tear through the black after you load in. Even if I wasn't looking around. It would start black. Then go to white, and have the smearing effect
ah the classic halls of mirrors effect from 1993 Doom. same reason too. nothing to render so it just render the previous frame
@@federicohansen4561
The way Cubemaps work is kind of weird. They are just a cube(a model, perhaps) that is barely any bigger than the camera's fov. It's just some trickery so it appears as a giant box. Perhaps when you delete all the models, the Cubemap isn't rendered at all.
This actually happens because the screen isn't being "cleared" for performance improvements (as in normal circumstances it would be useless because all pixels would be re drawn on)
The effect of the screen going from black to white might be a shader thing, as some effects (particularly auto-exposure) might change the brightness of the rendered pixels depending on the current brightness of the screen. That is, the algorithm sees a dark image, so it increases the brightness over and over until it's very bright
It's called... The void.
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.
the command "gl_clear 1" will cause the frame buffer to be cleared.

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.

My theory is that the game needs to be able to tell other players in the server what surface another player is on through playing these sounds. If your copy of the game can’t tell what surface you’re on then this information can’t be relayed to other players.

**Proceed to turned into a fly**
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.
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.
kinda agree, ngl

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

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.
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.

2:40 bruv thats some good kush he’s smokin
Ness used psi fire
@shounic A bit of a major correction here that I gotta point out
There's a HUGE reason why surface properties cannot be deleted - the physics engine uses them for calculating mass
If you think about it, a 1x1x1 meter block of concrete is going to weigh significantly more than a 1x1x1 block of Styrofoam right? In addition, the Styrofoam block is less dense and more airy.
So, the physics programmers at Valve figured that they could use surface prop type as a quick way to auto estimate mass when compiling a model, with a default no material backup being used with a density and weight of 1.
So by deleting the surface props.... you delete the custom densities and masses of objects and reset them to the default... which makes the physics bad....
So some quick foresight made it so that it just crashes the engine if there's no surface prop file.
Oh, it's also used for creating bullet decals.
Disclaimer: this is how it used to work (As far as I remember at least; it's been a long time) back in the old Source engine pre-Orange Box. I don't know if it was ever changed later, but I don't think it was.

I think it's much more likely that what happened was a programmer didn't think anyone was likely to delete that file, or the thought of deleting it never even occurred to them, so they didn't put in any error handling for that scenario.
Nah, there's an explicit requirement for that file to be present and unmodified, so that people don't edit footstep sounds and texture transparency. Cause that's an easy way to cheat.
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.

Why
"A programmer just decided to draw the line there"... more like the programmers wrote code that assumes those files exist, and they didn't worry about the case where the files are missing, because it's fair to assume players should have all the game files to play. It seems likely they could make the game work without surface properties files, but I don't see why they would be motivated to do that.
New maps introduce new textures all the time. Sometimes, these textures don't load properly. I wouldn't be able to play half the time if it weren't for that.
yet it works without everything else for some reason
surface properties is more complex than just step sounds, it identifies, well, what type of surface is the player interacting with, like if its a liquid or not, if its breakable, how heavy the object is, how much friction applies, how dense it is, wich impact decal should be used, etc
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.
The fact that you can mod sounds files, makes it so you can mod the sound of spy's cloak to be a constantly playing sound, or much more drawn out than it was, to assist you in detecting them.
Deleting the sounds is fine, modifying is not.

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
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.
