Possible case folding on material loading results in missing textures

[Tiagoquix]

In a custom map that I play, specific materials don't load for me, but the same issue doesn't happen with another person that plays on Windows. I play with the native Linux version.

I also remember playing this same map on Windows and having no issues on it.

The map is https://gamebanana.com/mods/72174.

Investigating the developer console reveals that it is unable to find the required textures, even though they're present in the map's BSP file. Here are the relevant messages from the developer console:

Here is a screenshot showing the messages and what's inside the map's BSP file:

I believe this happens due to case folding, considering how the messages in the developer console appear.

I am not sure if this happens in other Source games; I've only noticed it in TF2, but I believe this is a problem that has its roots in HL2 code (i.e. the Source Engine). And I'm also not sure if it happens on MacOS and the legacy 32-bit versions, but I know that it doesn't happen on Windows while it happens on Linux.

This also happens on another map, with more evidently missing textures.

The map is pkmn_goldenrodcity_b3. It's available to download at https://drive.proton.me/urls/RBBVTB79BR#6KMLuPgvFLTB (my local copy).

Strangely, the same issue doesn't happen when loading the same map using map workshop/1741035197 (https://steamcommunity.com/sharedfiles/filedetails/?id=1741035197) from the developer console (it's a reupload to the Steam Workshop). It only happens in my local copy.

To reiterate, these issues do not happen with Windows users.

This is probably a regression since I had not had any of these issues before an update (probably the Smimass 2024 update).

How it should look (Workshop version):

How it looks (my local copy, which was working 1:1 with Windows before some update):

Yea I can second this as a Linux user, it seemed to happen some time around early to mid-December for me though it might have started earlier.

This also happens on Trade_Minecraft_Realms_V2, missing textures everywhere.

I don't have a Windows PC or a Macbook to show this map on the Windows/MacOS version of TF2
The map download is here: https://gamebanana.com/mods/73762

This is on SteamOS, running the 64-bit version of the game.
According to the comments above, this issue only seems to happen on Linux.

I tested and found the issue. Is due to Linux not being able to handled if they are capitalized. I took a map and extracted all materials and renamed to lower and put it back in which resolved the whole issue.

Rather silly but works to manually fix it for now. Might create a script for it.

please make a script for it like now

please could someone report this issue too valve?
I can't even play zombie escape anymore because every time i try I get maps full of missing textures, error signs, and kliener saying "oh fiddlesticks what now?"

Maps are server-sided. Renaming the files in your client will make your map mismatch the map on the server (different file names), so it would be useless.

This GH issue is a report. We just need to wait. Soon™.

Maps are server-sided. Renaming the files in your client will make your map mismatch the map on the server (different file names), so it would be useless.

You can make a .vpk for the fixed files paths and just pray that the server is using sv_pure 0.

I can make a script if there is high demand but a easy way for now is get the map, open VPKEdit, save it, export materials, make VPK from folder.

It really sucks though, rip all the maps we used to love...

I tested for curiosity and changed proton from sniper to latest proton version, and somehow that resolved everything.

@Tiagoquix @DecibelHZ @CrashGround385 @Qwerty1235678 Would be good to verify, can you test and see if this helps you too?

You won't be able to join VAC protected servers with proton

You can still test locally by opening the map

you can't join any servers with proton dude...........
