iOS 11이 나오고 기존에 발매했던 앱들이 실행이 안 돼서 업데이트하던 중에 다음과 같은 에러를 봤습니다.

이전(발매 당시인 2-3년 전)에는 본 적이 없으니 코드상 문제는 아닌 것 같고 유니티 버전이 올라가서 그런 것 같은데 어딘지 몰라 헤매다가 겨우 찾아서 다른 분들 헤매지 마시길 바라는 마음에 몇 자 적습니다 ;ㅁ;

먼저 오류를 봅시다.

[Physics.PhysX] Cooking::cook/createTriangleMesh: user-provided triangle mesh descriptor is invalid!

피직스가 폴리곤을 생성하다가 보니까 유저가 제공한 폴리곤 설명자가 이상하다는 오류입니다. 유니티 2버전이었나부터 해서 지금껏 쓰면서 처음 보는 오류네요. 처음에는 당최 뭘 하라는 건지 몰라서 어브버 하다가 구글님 한테 물어보니 대충 답이 나오는군요.

문제는 컬라이더나 메시필터가 사용하는 메시의 모든 정점이 0,0,0에 있어서 그랬습니다. 크기가 없는 상태겠네요. 피직스 내부 동작은 잘 모르겠으나 이것 때문에 처리하는 데 문제가 생기는 것 같습니다. 여하튼 정점들이 값을 갖게끔 해주니 말끔히 사라집니다.
