Lorsque vous souhaitez utiliser l’ensemble d’outils dans la salle UV , votre mod\u00e8le aura d\u00e9j\u00e0 re\u00e7u une certaine forme de topologie et une disposition provisoire de la carte UV – bas\u00e9e sur le “D\u00e9veloppement” que vous avez effectu\u00e9 dans la salle Retopo .<\/p>\n\n\n\n

Dans ce contexte, le “Menu Texture” appara\u00eet dans le panneau du menu principal avec une liste de fonctions “Import”.<\/p>\n\n\n\n

Comme vous pouvez le constater, toutes ces fonctions Import traitent de l’importation de textures individuelles ou de calques de texture. Apr\u00e8s avoir cr\u00e9\u00e9 une carte UV , la prochaine \u00e9tape logique consiste \u00e0 cr\u00e9er des couches de texture qui peuvent ensuite \u00eatre export\u00e9es avec votre mod\u00e8le nouvellement topologis\u00e9. Et, si des textures ont d\u00e9j\u00e0 \u00e9t\u00e9 cr\u00e9\u00e9es pour ce mod\u00e8le, le menu Texture devient disponible pour les import .<\/p>\n\n\n\n

Dans la bo\u00eete de dialogue d’ouverture, il existe \u00e9galement une option intitul\u00e9e\u00a0:
Mod\u00e8le de carte UV , qui, s’il est s\u00e9lectionn\u00e9, ouvre la bo\u00eete de dialogue “Import pour la Painting par Per-Pixel ” – vous permettant d’ import un mod\u00e8le avec des UVs existants qui peuvent \u00eatre modifi\u00e9s dans la chambre UV .<\/p>\n\n\n\n

par ALEX MEISTER:<\/p>\n\n\n\n

Tout d’abord, nous devons import notre mod\u00e8le 3D dans 3DCoat via l’option “UV Map Mesh” dans le menu de lancement rapide – cela ouvrira la fen\u00eatre contextuelle Import un objet\u00a0: <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

J’ai tendance \u00e0 s\u00e9lectionner l’option “Verrouiller les normales” car je le veux exactement tel que je l’ai export\u00e9. (Si vous ne les conservez pas, cela changera la plupart des normales en lissage): <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Le type de carte UV peut \u00eatre modifi\u00e9 pour cr\u00e9er une nouvelle carte UV , qui cr\u00e9era un mappage automatique.<\/p>\n\n\n\n

Dans mon cas, j’ai d\u00e9j\u00e0 d\u00e9fini 4 cartes UV , donc je voulais les garder, car je les referai de toute fa\u00e7on plus tard (juste une simple carte automatique dans Maya pour avoir quelque chose dedans).<\/p>\n\n\n\n

Maintenant que notre mod\u00e8le est charg\u00e9 et configur\u00e9, nous passons \u00e0 la section UV (si elle n’y est pas d\u00e9j\u00e0, surlign\u00e9e en orange). Comme vous pouvez le voir dans l’aper\u00e7u UV (qui peut \u00eatre activ\u00e9 sous Windows – panneaux), notre UV a l’air plut\u00f4t mauvais. Il a trop de coutures, et cela nous donnera plus de mal \u00e0 les texturer correctement – alors am\u00e9liorons-le.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Mappage automatique \/ coutures automatiques <\/a><\/h3>\n\n\n\n

Il y a plusieurs fa\u00e7ons de faire des UVs \u00e0 partir de maintenant, la plus rapide mais probablement la pire est l’automap car elle a tendance \u00e0 cr\u00e9er beaucoup trop de groupes UV . Mais cela peut \u00eatre utile dans certains cas o\u00f9 vous ne voulez pas y consacrer beaucoup de temps. Si vous \u00eates satisfait des r\u00e9sultats, passez \u00e0 \u00abexport\u00bb.<\/p>\n\n\n\n

Auto Seams est l\u00e9g\u00e8rement la meilleure option mais a tendance \u00e0 se tromper sur quelques pi\u00e8ces, alors allez \u00e0 “marquer les coutures\/boucles de bord” pour r\u00e9parer les \u00e9ventuelles “mauvaises” pi\u00e8ces. Les pi\u00e8ces particuli\u00e8rement organiques ne sont g\u00e9n\u00e9ralement pas cartographi\u00e9es de la meilleure fa\u00e7on. <\/p>\n\n\n\n

Boucles de bord \/ Coutures de marque <\/a><\/h3>\n\n\n\n

Ma partie pr\u00e9f\u00e9r\u00e9e de 3DCoat est Mark Seams ; tandis que la boucle d’ar\u00eate fait essentiellement la m\u00eame chose, les coutures de marque peuvent s\u00e9lectionner juste une partie d’une boucle ou la totalit\u00e9 de la boucle d’ar\u00eate en appuyant sur le modificateur de d\u00e9calage.<\/p>\n\n\n\n

Comment \u00e7a marche? Simple, apr\u00e8s avoir import votre mod\u00e8le, appuyez sur “clear Seams”, ATTENTION cela supprimera tous vos bords UV ! (et cr\u00e9ez quelque chose comme l’image \u00e0 droite) Ensuite, vous cr\u00e9ez des coutures l\u00e0 o\u00f9 vous pensez qu’elles doivent \u00eatre et o\u00f9 elles ne causeront pas de probl\u00e8mes.<\/p>\n\n\n\n

Le clic gauche s\u00e9lectionne simplement le bord.
Ctrl + clic gauche supprime une ar\u00eate.
Maj + clic gauche a cr\u00e9\u00e9 une boucle d’ar\u00eate
Ctrl + Maj + clic gauche supprime une boucle d’ar\u00eate
Cela peut sembler un peu \u00e9trange au d\u00e9but, mais cela devient simple apr\u00e8s quelques utilisations et vous donne un contr\u00f4le \u00e0 100 % sur l’endroit o\u00f9 vos coutures doivent \u00eatre cr\u00e9\u00e9es.<\/p>\n\n\n\n
