<div name="quoted-content">
hello,<br/>
<br/>
you have to manually adjust the position of the 4 vertices defining the corned of the primitive in order to spacially adjust them.<br/>
then, you have to adjust the position of the teture in this point (it's an option that you don't really need).<br/>
here it is adjusted in a neutral position.<br/>
