I see in some posts they say that you can edit the mesh manual to do X, Ive tried opening the mesh with a text editor and its just garble is the a specific program I should use to edit these?
You cannot edit a mesh YET. You can edit the xml though. That's where all your settings and hotspots are
Notepad++ advised http://notepad-plus.sourceforge.net/ (as u can open alot more files with that one and have it colorcoded according to the language used).
