I just bought a 512x512 ground texture from the torishop. Turns out that it doesnt show up ingame. I also found another player who had the same problem. Is this a thing? I am using the newest steam version of the game.

I believe theres a command for this, its /opt groundtexture 1 I think.
try that

That doesn´t work. Says invalid option.

my bad sorry.
its /opt floortexture 1 or /floortexture 1

clicky

I tried all of that stuff. It still does not display. Maybe something is wrong with the game? As I said I met other people on multiplayer who have the exact same problem.

what version are you using? It might just be buggy, have you tried /dl and /lp yourself?

As stated in my post I am using the newest steam version. yes I tried that.

Try deleting your custom file then DL'ing yourself again.

Tried that didn´t work either. Can you try to /dl /lp me and tell me if you see my ground texture?

did that and I cant see anything. Weird
try deactivating and activating it a few times
