Re-textured Meta Cubes for WorldEdit / Creative

If you are working with schematics a lot, these fancy meta cubes will probably be more pleasing to your eye,
plus they do have a higher contrast which will provide a better overview of things.

Will also add the new "invisible barrier" block, to prevent players and creatures from trespassing
plus you'll now have descriptions to every meta block.

This is a   stand-alone version   of a mod that is already included in the 'CoB' Server Pack.
