but don't forget that in the code the line;
xform -scale 0.7 0 0.7;
should actually read;
xform -scale 0.7 1 0.7;
As always I hope you enjoy it or at least if you can't enjoy it that you get something out of it. If you have any questions or aren't sure about my explanations for any part of the tute please get in touch and I'll try and explain myself better!
