Questions about the CLASS UPointSetComponent

Hello,
I am trying to use a lot of points to simulate a starry sky. I found it slow even if I used a two-triangle plane when the transformation of each instance is updated every frame. So I turned to the class UPointSetComponent. BUT I cannot compile it on VS2019 with UE4_26 and I failed to find any examples about it.

An error message would go a long way… but anyways, just use a particle system. It’s going to a 100 times more efficient and easier.
