Continuing the discussion from Project a pattern:
Hey bro,probably you are a great professor or engineer now. 
Maybe I’m doing the samilar research with you. I got the same trouble and I can not get any thing changed after press F12. The partton can be projected without distoration by adding maooing and other nodes but the main problem is the sacle that mentioned by chipmasque. the projected patton is always square automatically， even the input is rectangle。And it makes the internal parameters hard to be solved. Can you help reason9499 find out the reason? 
thanks a lot.
