Hello,

I'm a fashion and graphic designer and I really need to know and learn how to create clothes for poser and Daz studio 3d models. I'm willing to learn, please help me with links and tutorials.

Thanks

That's probably the single most difficult task you could undertake.

You'll need a modelling program of some kind.  There are plenty to choose from, in prices from free to thousands.  At the free end of the scale there are Wings, Blender and Anim8or (and probably several others).  Pricier options are Maya, Lightwave, 3D Studio Max.  Somewhere in the middle there are things like Hexagon.

Then, you have to learn to use 'em.  Each one has a different learning curve.  I'm currently using Wings and it's dead easy to get to grips with, IMO.  Some people can't get on with it, however.

After you've made your model, you have to UV map it.  You'll need UVMapper; there's a free version and a bigger brother, UVMapper Pro, which ain't free.

After that, you'll have to rig the model to enable it to bend in Poser as clothes should do.

www.wings3d.com will get you Wings

www.philc.net has tons of tutorials
 
http://www.morphography.uk.vu/ has tutorials and starter meshes

I'm certain you'll get more info and advice as the day wears on.

While you're at PhilC's site, check out Clothing Designer which is designed to make it easy to, er, design clothes within Poser without knowing modelling. The downside is some loss of flexibility, since there's no way Phil can foresee everything you might want to do and build it in from the outset. DAZ|Studio can use Poser figures, and currently it can't do rigging or dynamic cloth simulation; so you'd want to concentrate your efforts on Poser, I think.
