[C++]Item Path Mesh not working with blueprint?

Hello,

I have ItemObject class with a path for the mesh directory.

When the class is loaded, it take the path to find the mesh.

Now I want to make a child class of this class in blueprint.
So I have just to set the path to have the mesh.

But when I reload everything, it say:

I dont understand because it work when a put the path directly in the code !

Thanks, sorry for my bad english :frowning:

Sorry, but I can’t select wich mesh I will use with TSubclass. When I drop down the menu I can choose between StaticMesh or None :confused:
