O processo de criação de um modelo de jogo 3D Hard Surface

Capítulo 1 Introdução

Decidi escrever aqui um pequeno (enorme) artigo sobre como faço modelos de jogos. Em geral, comecei a fazer essa arma, e me veio a ideia de que poderia tentar descrever todo o processo, de repente seria útil para alguém. Este não é apenas meu primeiro artigo, mas também meu primeiro trabalho como designer.

Havia muita informação aqui, será difícil para os iniciantes aprenderem tudo de uma vez, mas tentei transmitir tudo na linguagem mais simples. Espero que este artigo ajude alguém, talvez não tanto a trabalhar nisso, mas talvez busque maneiras mais rápidas e eficientes. Obrigado pela atenção.
