Unifying UV texture across several objects?

Is there a way to unify an UV texture across several separate objects? I’m toying around with the fracture tools and I’d like my shards to have the original texture of the cube.

Still waiting for an answer.

While you’re waiting look up the use of the render bake options. If you want to consolidate separate textures into one you can use the consolidate function in the Texture Paint Plus addon.
