Look at the image attached. I had this surface, which is maed of several levels of boolean operations and face extruding, and then I applied a Lambert material to it, and then a 2D texture called wall7 (which I got from the Shader Library).
Why is it all scrambled? Which parameters should I change to get it working correctly?
I have already tried a lot of differente setting, but as I`m a complete newbie, I can`t get it right!
Thank you very much
