Meshcacher

Introduction

Meshcacher is for use with Linked groups and proxies, replacing them with pc2 caches and local meshes with the mesh cache modifier. It can also optionally remove (actually just hides objects and remove group duplis) the original linked group/proxy. The reasons for doing this are:

1. Simplify away rigging details and just use simple caches (can be faster)
2. Allows local modifications of the meshes (bypassing the limitation of linked groups that does not allow local modifications)
3. Easy retiming of animation by automatically driving all meshcache modifiers by a single empty
4. Allow duplication of animated characters or objects with different animations (also bypassing a blender limitation with linked groups)
