Issue with textures after packaging

I am using the LandscapeAutoMaterial. from the editor everything works fine. I tried to package it and the grass looks like is not rendering correctly. I included the directory where the texture is (the whole LandscapeAutoMaterial directory) and it’s still not working. How can I find out what the issue is? is there a log or can I generate a log to figure out what’s missing or where the game is expecting to find the textures once packaged?

I apologize if this is not the right forum to ask this question …

thanks!
