How do you make avatar like this?

Well, its called a "Joint-render".
You can request one at the art/textures section [ If its still allowed to take requests]

OK...I'll try and how to get hector relax?

You must buy it for 1-12kk tcs

It isnt worth 1 mil tc.

Well, is there any complete or full tutorial to make these 'joint-render'?
