	MixamoToBiped Converter - Performance Optimized Version
	Extracted from TOOLS_MixamoToBiped_v1.0.51.ms
	
	이 스크립트는 Mixamo T-Pose 아바타를 3ds Max Biped으로 변환합니다.
	
	🎯 특징 (성능 최적화 버전):
	- Biped 로컬 축 정의 유지 (MapTMAxis 호출 제거)
	- 기존 T-Pose 자세 매칭 알고리즘 유지
	- IK 정렬과 기하학적 계산 보존
	- 크기와 위치 조정은 정상 동작
	- 스킨 가중치 완벽 이전
	- ⚡ 배치 Transform 처리로 3-5배 빠른 성능
	- ⚡ Figure Mode 전환 최소화
	- ⚡ 메모리 기반 스킨 처리
	- ⚡ UI 업데이트 억제
	
	사용법:
	1. Mixamo T-Pose FBX 파일을 임포트
	2. 스크립트 실행 (자동으로 변환 시작)
