Unwrap Separate Meshes I have so many books models to texture. Texturing them one by one will be a pain. Can Blender unwrap two (or more) separate meshes and make them share the same UV grid?
As long as all the vertices in your objects are completely connected to each other (no loose parts) the following technique will work:


Select all your objects, and press CtrlJ. This will join them into one  mesh.
Press U > Unwrap (or whatever unwrapping method you want use).
Press P > Separate by Loose Parts.




This works great for quick 'n' dirty unwrapping onto a tileable image, but it may make more sense to link them all (like Matt said). The simplest way to link them early in a project is to duplicate them with AltD instead of ShiftD. It will link the mesh and the UV map which will make things easier later on.
