Topic is the question I got.
I have got 6 cubemap textures (1 for each direction), that are not flipped (It seems that cubemap textures don´t have to be flipped in order to be drawn correct in OpenGL, right?).
Now I want to use these 6 textures for a skybox and then they have to be flipped, right?
The question is how can I do this via the texture matrix, so that I don´t need 12 textures (6 cubemap textures and these 6 flipped, so that they are suitable for the skybox)!
