unity3 changes---------------Build Pipeline

Build Pipeline: Typetrees are removed from serialized files (assets) when possible, this make resource files smaller and loading time faster.

i want to know if all my assetbundl from 2.6x need to be rebuild…?

You should rebuild the bundles (there are also other problems that can occur if you use old bundles).

OMG…that’s terrible

the assetbundl from unity2.6x can be loaded in unity3 editor,but can’t be loaded in win exe which i was build by unity3.
tell me why…
