How can I make a compiling shaders/loading screen?

Hi,
I’m trying to do a main menu that at same time is a loading screen.
What I mean is that I want that the game load in the main scren and there it does the shader compilation of the main level, the problem is that when I tried to do a shader compilation counter it does not count correctly and either my main map don t have shaders compiled.
that s the blueprint part where is supposed to count shader compilation(is not refined jet, I m trying different things)
