I am trying to find a way to add a texture on a Face to create a more simplified model.
The problem is that I can't scale the texture to fully cover one side of the model.

Basicly the idea is to make images, Top/Front/Left, from the original design (example1), to later attach those images as a texture on a very simple extrude (example2).

Though whatever I tried, I'm not able to get the texture, in the right scale, on the extrude.

Is there a good way to do this? or is there a more simple way?
