Hi
This is my 1st attempt at modeling a car/vehicle, Im used to modeling Humanoid forms in low poly...
My problem is, after roughing at the shape in prep for meshsmooth I want to place the the creases into the car as i like to model as 1 peice and not lots of multiple parts. I read Onno's tut on this..sounded simple enough but its all going pear shaped where lines cross each other.
Onno recommended chamfering, extruding then chamfering again and if lines cross to do them all at once but i get some funky curved effect going on and its really frustrating me.
I ve added 3 screens for you guys to look at, screen1 shows the edges chamfred and 2+3 show the result which is slowing my progress.
Simpleton terms or drawing on the pics would b best

If u require more pics i can post em. A
*I only performed part of the process to show the worst problem area*
Regards
Hinch
