I have looked for a solution for a little while now however I'm not sure if other people have encountered my same problem. I am trying to draw a skybox in a blank opengl window, I have camera controls and I can zoom out and see the skybox is there but not being textured correctly/ at all. I have used code from opengl and I have only tried to implement it into a class.

Skybox.h

{

    Skybox();
    ~Skybox();

I am using an M2 Macbook and I do not have a shader class like I have seen a lot of people use, I implement my shaders the way my lecturer has done so. I hope I have provided enough and thank you in advance if anyone can help!
