Hi,
I did some try and error and got an approximate value for the length of my
string. Now I added the billboarding behavior.
Unfortunatelay my "left" labels are rotating around the new adjusted
x-coordinate, and not around the point.
Is there another way to place Text2D shapes on the "left" of my point
coordinate? Can I tell Text2D somehow to align_last?
Thanks for your help in advance.
