HaloMods "Classic" Read-only Archive

Well here I m up to no good agian trying to do something special but right now I need some help. I would like to add a reflexive to the hlmt tag so I can add chunks to a specfic thing. However I am not sure what to use to find the Size and the location. Can someone be kind enough to give a smalll tut?

Thanks

use entity to find the location and size, just remember to add 4 to the offset though.
