Hello,
I am trying to draw a grass according to the following tutorial:
https://docs.unrealengine.com/en-US/Engine/OpenWorldTools/Grass/QuickStart/4/index.html
I went through all steps in tutorial and managed to draw and see grass:
But after I press Build button:

Grass become flat:

My question is why it happens after Build operation and how to fix that (how to see grass after Build operation)
Thanks.
