PBR Guide

● ES2.0�수준의모바일쉐이더를ES3.1을최대한활용하는수준으로업그레이드

● Substance에서작업하는결과물이최대한게임에서의상태와비슷하게세팅

● 기본적이고공통적인Material�을최대한단순하게구성

● Megascan같은실사아트애셋을최대한많이구매

● 엔진프로그래머는거들뿐결국아트팀의이해와능력이중요

ComparisonBlueprint 는축복

● 누구나쉽게접근가능

● 빠른컴파일속도

● 빠른개발주기

● 기획자들은좋아할듯

Blueprint 는대재앙

● 협업의어려움

● 구조화가어려움

● 가독성이떨어짐

● 프로그래머들은싫어할듯

#UE4 | @UNREALENGINE

Blueprint최소한으로만써요
