Le processus de création d'un modèle de jeu 3D Hard Surface

Chapitre 1 Introduction

J'ai décidé d'écrire ici un petit (énorme) article sur la façon dont je fabrique des modèles de jeux. En général, j'ai commencé à fabriquer cette arme, et la pensée m'est venue que je pourrais essayer de décrire tout le processus, du coup cela serait utile à quelqu'un. Ce n'est pas seulement mon premier article, mais aussi mon premier travail en tant que designer.

Il y avait beaucoup d'informations ici, il sera difficile pour les débutants de tout apprendre à la fois, mais j'ai essayé de tout transmettre dans le langage le plus simple. J'espère que cet article aidera quelqu'un, peut-être pas tellement à y travailler, mais peut-être à chercher des moyens plus rapides et plus efficaces. Merci pour l'attention.
