Put both the ssjvegeta.mdl file and ssjvegetaT.mdl file into the your ssjvegeta folder.
I recommend making backups of all the files you're going to replace.
Important Note:
Type cam_idealdist into the console and give it a value of around 275. This
way you won't just see his legs. I suggest binding this to a key as well as
binding cam_idealdist with the original value of 40 to another unused key.
