I did the tutorial http://cgcookie.com/blender/2012/12/14/creating-uniformity-particles-blender/ without any trouble. But when I attempted to apply the technique to my own image, I couldn’t get the windows to face in the right direction. I moved the window’s origin point to several positions and the orientation of the window itself too. But I can’t get the windows to face out like they should. Can someone tell me what I am doing wrong?
