For your materials to work properly at render time make sure your textures have a valid file path (Source File in the texture Details panel). V-Ray loads the textures from that directory during rendering. If the texture is not found at the specified location, V-Ray will automatically export the texture. You can then find it in your project folder > Content > Texture Cache.
