Textures not showing

  • Hello. I´m having some problems with certain textures.
    Some materials display properly and some just don´t. I get the ones that do and swap the texture image with the ones that don´t and then they don´t show anymore.
    I thought it was from my side making bad files, but I recalled it is happening also with proper VW materials.
    Is this a known issue?
    Can you provide help, please?
