Several (but not all) of my custom textures do not show up ingame in my CS map, but rather as the pink and black checkerboard. I've tried solutions such as reduced texture size and renaming some of the textures differently (in Wally), then replacing the wad and retexturing the brush. None of these attempts worked. A 64 x 64 texture doesn't show up for example.
Does anyone know what could be causing this? Is it perhaps videocard/driver related, or might it have something to do with how i made/edited the textures and saved them into a wad in Wally?
