Cool but maybe this will better if you had put each step in a scene(page)

Can you use some texture like this or must it be tiling seamless?
(here Zbrush doodling)you can find some on my "Speedy galerie" free to you to use them

Maybe by : Kmz-->Blender-->OBJ (or 3DS) ?

take a look here 3D Converter(50$ or 40€)
Maybe some format like OBJ, IGES can work

Take a look at this link
Some videos are on your subject (use the "research on the page" of your navigator)
Normally only 2 corners are sufficent

That is some fractal if your abstract sculptures often provide interesting textures for your building models

sorry, what does "NPR" mean?

No Photo (hyper) Realistic style (?)

Sixties style indeed, can be used by skaters

Mais non ta première ébauche est très bien, suffit de continuer!
Tu avais réussi a faire des parois pleines courbes en bas !
Pas de raison que cela ne marche pas pour les parties hautes!

La modélisation c'est un bricolage perpétuel, il n'y a pas de recette miracle!
Que de la persévérance : prends ton temps, fais des copier coller de parties bonnes, retourne-les, bouge les arêtes, et cela viendra tout seul avec de l'entrainement!
Utilse aussi l'outil "Follow me" : une face perpendiculaire que l'on propoge le long d'une courbe
(sélection du chemin, clic sur l'icône, clic sur la facette) et hop voila un tubage qui peut avoir quasi toute les formes
Regarde ce post
Voila une manière "d'arrondir" tes formes

Il y a une manière très simple!
Il suffit de donner de l'épaisseur à tes parois!
Le ruby script "Joint Push Pull" JPP pour les intimes est ton ami
Tu fais "voir la géometrie cachée", tu sélectionnes tes facettes et t'appelles le script!
Ultra puissant comme outil!
Après t'as plus qu'à déplacer tes arêtes pour avoir ta forme souhaitée tubulo nervurée

En plus c'est un francophone qui l'a créé Fredo6 (la dernière version est accessible en bas de page du fil de discussion!

and from a bit of distance they seem to tile really badly (not to speak about the nasty moire effect)

You have some buttons like "seed" for choice another variations of forms
and other for increase or attenuate the nasty moire effect
and the tiling itself is "perfect"!

Unnatural
maybe it's just procedural

Take a look in the free procedural Genetica Viewer terrific free prog and very easy size 3000*3000 if you want
And this free Wood WorkShop
Have seamless tiling texturing

Ps A little trick : load the pro version 30 days of Genetica and copy the content folders "Viewer Presets" et "Wgroups" in Genetica Viewer so will have a whole bunch of textures

GE is Google Earth ?

Look this one

Does the mesh can be less detailed (number of facets) for a same result of texturing or this one is the minimum?

y en a là mais faut chercher un peu ou là

It's the "Apple's skin" the danger : just 27 pesticides inside for a normal apple: so you must peel the apples
