All of the components derived from UPrimitiveComponent have a specific function.
I simply want to draw a texture/material component over my actor, with the possibility to change its location and rotation.
UMaterialBillboardComponent works fine but i dont need the behaviour of facing the players camera.
I know there are more ways to solve my problem, but what is recommended?
Finally i got it to work with the a widget blueprint. Added the widget as component to the actor and changed its rotation/location in tick.
