Your guess is right, dude
actually, i know wow maybe can import other M2 model, i found it in "TomTom"addon , yep, that small arrow,
but now, i have no time to understanding how to use it, like BLZ allow how to rendering it, and these M2 model how rotating, etc.
so i cut corners just use pictures sequence, WeakAuras can solve this problem simply, certainly, that's EVN and Ironi taught me

and, did you see the oUF Donut? that's your work, in fact that this is amazing , i very appreciate your excellent addon
oh, target arrows, you are right, i use NPA2, it's very easy to achieve this effect, and that is an awesome plugin too.
