Document about Render target height field painter

Hi I’m FXartist from Korea. I’m using 4.20.
I try to make energy shield material witch can be interaction expression on the hit point.
So I searched about Render Target. and I found UnrealDocument about it. and I tried their Tutorial.

But, in 'making height field painter’part. there is strange things.
In this Document, there is 2 method. And I have to choose second method.
My mesh isn’t planar shape. And, I have to copy the codes and paste to my blueprint.
But there is node named ‘Apply paint’ and it doesn’t compile.

And when I copy and paste second codes, engine crashed.
I tried to find English version of this page. But there isn’t.

I found this things in ContentExample. But blueprints in this project is for planar shape. so, doesn’t works for me.
If there other ways to do this RenderTarget work please let me know.
