쉐이더를 자동 생성해주는 MEL.
JSH_TEXTURE_SHADOW_OCC_DEPTH_SHADER_MAKER_V1.0
일명 판맵을 이용한 씬 구성에서 쉐도우와 오클루젼과 뎁스를 뽑기 위해 만든 MEL입니다.
컬러 텍스쳐 이미지의 알파값을 이용해 오브젝트마다 쉐도우 쉐이더를 일괄적으로 만들어 적용시킵니다.
즉, 오브젝트 갯수만큼 쉐이더가 생깁니다.
JSH_TEXTURE_SHADOW_OCC_DEPTH_SHADER_MAKER_V1.0.mel 실행 화면아래 소스 공개이며
첨부파일 다운 받아 마야로 Drag&Drop하면 실행 됩니다.

/*** JSH_Make_TEXTURE_OCC_SHADOW V1.0 ***********************************************************************************************
제작자 : 정순홍, KBS 미디어텍 특수영상부(본 멜 스크립트는 저작권을 행사합니다)
버전 0.9 : shadow만 처리, OCC는 V1.0에 추가 예정
버전 1.0 : shadow에 이어 occlusion, depth 기능 추가
설명 : 텍스쳐, 맵소스로 제작된 씬에서 그림자, 오클루젼, 뎁스 를 뽑기 위해 usebackground를 자동 생성하고 기존 텍스쳐를 이용해 알파 마스크를 연결하여 쉐이딩을 자동으로 해줌.
사용법 : 1. 적용할 오브젝트를 모두 선택한 뒤
2. MEL 스크립트 파일을 마우스로 끌어다 창에다 떨어뜨리면 됨 (drag&drop)
3. 자동으로 해당 오브젝트별로 usebackground를 만들어 적용을 시켜줌.
