Basically the *align* tool from 3dsmax.
Its always bugged me that vbsp reports these as warnings during compile, but gives you no clue to finding them, and Hammer doesnt recognise them as a problem.
Its really handy for working on them and preview, but can be annoying and performance killing having a lot of them animating all at once.
