lol not wanting to change much lol
no the nameplate is provided by discord unit frames, type /duf and you will get a window click self at the top and down the side you have various options, in one of the texts i forget which
but click one of the texts i think its text1 to the right of that the window options will change slightly you have basic and special options in the special you will see some text like $nm $lv $cl
to remove your name delete the part only that says $nm
you can also use the options in /duf to change the look of your bars but that one sir is up to you lol, took me hours-no days to config the whole thing
for the 3d models you need to type /zmob config and while holding shift, right click the portrait and drag to resize
ope this all helps
