Hey Jay, Nice compilation of work on your site, like the idea btw... Well ill post some links then instead, to my problem with this pipe im bending.. Pinching - can not get rid of it... https://img89.imageshack.us/img89/699...60124346ur.jpg What I have tried > Its a nurbs cylinder with 8 sections/10 spans as per tutorial, select object mode is vertices, as per tutorial. Select one span of vertices or 2 etc and use the move tool to bend the pipe up and out etc etc... I end up with pinching and discolouration, the tutorial dvd does not show any pinching... Ive never had this when I used to do pipe work so im unsure why I am now.. Im in selection 3 mode for the wireframe and then 5 for shading. Here it is again also showing shading options, I have tried altering the general prefs/nurbs shader definition slider from default 4 to 8 etc to see if I can see any changes, but nothing. https://img157.imageshack.us/img157/2...62305508ob.jpg Any ideas why, the instructors pipe in perpective mode etc does not show that horridness and I really dislike modeling like that as it gives such a bad representation of what you are doing.. Here is the tutors pipe. As you see its not even showing any stress at all, but ive got exact object specs as he has. https://img241.imageshack.us/my.php?image=tutors5il.jpg Any info/sudgestions really really appreciated...
