Unity Mega Fiers導入PC2文件失敗

1.前言
  如何導入看這篇文章，鏈接，講的很清楚了
2.問題及解決
  出現mapping of XXX failed,查了好多資料，最後還是好不容易翻牆找到了官網才知道，這個也太偏僻了

	Make sure you are using local space point cache files, so for example
if you are using Max make sure you use the Object Space Point Cache 
Modifier as opposed to the World Space version and in other packages 
be sure to click the local space option box in the exporters.
	Also if you have Mapping Failures check to see if the Optimize Mesh
option is turned off in the Unity FBX import settings.

第一種是座標問題，我是第二種情況，這個勾去掉就ok

還有，我補充一句，添加point cache組件的object一定是max裏用點緩存的，也就是說，該是哪個物體就給哪個物體，這個不要給了父物體
