Need some help positioning a text layer

Hi, I need some help positioning a text layer in my DX world.
I have a 3d World and I want a text to be placed next to a point. That’s quite easy with a translate node, but I want the text to always “look” at the spectator.
I already tried “lookAt”, but it didn’t really work, I don’t know why…
I also tried inversing the projection matrix but it still didn’t work… I’m a bit confused with all those transform things…
Could someone help me, please?

try Billboard (Transform)

Thanks for the fast answer! Works!
