CGTalk - normalizing maps

ok dudes,
simple question
1)i model a bottle(revolve).
2)map a checker with tiling 10 in u and v
question:how do i go about normalizing the texture on the nurbs surface so that it is uniform all throughout irespective of how the spans are layed out....i.e no distorting recatngles.
cheker texture should be near squares.
do i have to rebuild ??? if so what kind of options should i use.

and while i'm nit picking your brains migh as well ask...
say i'm modellig a head the nurbs way(gulp!!!) so generally i'd do it in seperate patches because i'd get localised detail where i wanted to(nose,mouth) and not every where(fore head,scalp etc)...fine.but(ah ha) to keep these pieces together i need to stich them ??? if yes then dosent stitching require the patches to have the same parametrization and same no. of spans to work successfully ???dosent all this fall apart when animating???
i might sound out of my rockers here but if any body has done a head in seperate patches(nurbs) and pulled off animating it and texturing it satisfactorily then do let me know and give me hope, joanna give me hope, joannah till the patchings done ;)
thanx...a lot

1. in the AE of the surface open the folder "Texture Map" and check "Fix Texture Wrap". unfortunality this doesn't work all the time. you could also try to build all your surface with "chord length" instead of "uniform". but at last it's the way nurbs is handeling texture spaces. it has always texture coordinates but they might be not always in the most perfect layout.

2. yes you're right. they should have the same parametrizations to succesfully stitch :)

thanx,
i guess nurbs will phase out in the charachter animation area with subdivision geting stronger and stronger with every version.
i wonder when the time will come(which version of maya) when i can draw a curve(and extract one) on a subdivision surface like on a nurbs surface...mann that will be the day i say bye bye nurbs :
thanx

noo :)

let's say all together in chorus "WE ALL LOVE NURBS" :)

there will always be a place for nurbs. ok characters will switch do subds, but cars, design stuff etc. nurbs is the weapon of choice and will be :)

Wooah! PA is so sweet. The nurbs just god damn work. And I kind of liked the keypoint curves too, very good for non-organic surfaces. :buttrock:

I remember when I first got to know the concept of marking menus. Blew my head off. Now I could not live without them. :airguitar
