Can you convert .mesh files using convertdata as well? I did something to convert them, haha, but now i forgot, is that silly or what? Sorry, but im trying to convert 1.12 binary .mesh to text .mesh (so as to use the resize tool on them) 
Beta 2 kept crashing, so i am back at 1.12 for now until things smooth out.
Thank you for the help and time too,
Sincerely,
