Hi ! I love this pack ! Tho I don’t see the wall texture that is present in your images, did you changed it ?
Hi! Thank you!
It seems to still be there in the "textures" folder, named: "wall_6".
It's possible that I have changed the texture of the modular walls to some other texture for the most recent update, but I see I didn't remove the previous texture from the folder, so you can simply assign that texture to the shared material of the walls inside the game engine that you're using.
