Thanks a lot for your interest.
Now I understand better what pass on the textures.
Actually I can’t imagine your solutions in my workflow because they are more complicated than to make a projection in cube projection and have the textures coordinates in UV. RickyBlender’s solution take the time and need 3 materials with the assigment. CgCody’s solution loose the result when you apply rotation on you model (often needed).
There is’nt a possibility to just rotate the image in Blender without changing the method of assigmend on the model?
Have a good day!
