How Do I Make All Characters A Block Mesh?

I want to make all characters have a block mesh to match some of my gear. I've tried some scripts from the toolbox but it hasn't worked very well. Can anyone help with that? Here is a link to a reference I found.

Hey.

BlockMesh's cant have IDs in them, so use SpecialMesh's instead. :)
