Wire-frame Issue? Shader or Texture?

[vocal solstice]

I don't know if this is a common issue, but I've been getting some wireframed floors instead of actual floor textures. I assumed it was a texture mod that replaces missing textures and Errors but it didn't fix the issue (I deleted any missing texture replacements).

• I have already verified the integrity of my files, but it still persists. I also assume this wire frame bug also applies to the other maps I've downloaded but I've not yet seen.
• I have L4D2, Portal, CSS, and HL2 EP1&2 Sources as well, So I don't think it's a missing resource issue?
• I already tried to delete the game and reinstalling it, but it didn't work.

Maps used in the photos:
Map 1: "Your Friend Last Day | Horror Map")
Map 2 : "Vert Portal") - Floor made random colours as I shot it

Any suggestions or ideas will help immensely, I just want this issue fixed.

have you tried playing with -noaddons -noworkshop in your launch parameters to see if it works without addons, and is an addon issue?

It's hard to say, these wireframed textures don't appear on gm_construct or gm_flatgrass

But I haven't seen if it affected Hlaf Life maps

Do you have this installed? https://steamcommunity.com/sharedfiles/filedetails/?id=3342334750

I had wireframe issues with it before.

OHHH yes, I have this Map

I'm going to see if this caused the issue
