I tried that tutorial a long time ago.and I think with the paremetric mapping mode it works fine or do it twice one mask for top and one for bottom of model then in the texture editor hold ctrl while selecting the dot in the second column and it should map it twice column 1 for bottom column 2 for top. I would say try the tut. and maybe wright Peter directly if you have prollems. Good luck
