가상 텍스처링 스트리밍(SVT)은 씬에 고해상도 텍스처가 많을 때 GPU 메모리 사용량과 텍스처 로드 시간을 줄이는 기능입니다. 이 기능은 텍스처를 타일로 분할하고, 필요할 때 분할된 타일을 GPU 메모리에 점진적으로 업로드합니다.
SVT를 사용하면 고정 메모리 비용을 설정할 수 있습니다. 전체 텍스처 품질의 경우 필요한 GPU 캐시 크기는 씬의 텍스처 개수나 해상도가 아니라, 주로 프레임 해상도에 의해 결정됩니다. 씬에 고해상도 텍스처가 많을수록 SVT를 통해 더 많은 GPU 메모리를 절약할 수 있습니다.
SVT는 Granite SDK 런타임을 사용합니다. 워크플로에는 추가 임포트 시간, 추가 빌드 단계, 추가 스트리밍 파일이 필요하지 않습니다. Unity 에디터에서 일반 Unity 텍스처로 작업하며, Unity는 프로젝트를 빌드할 때 Granite SDK 스트리밍 파일을 생성합니다.
