Packaging Failed "Landscape AUTO Material"

Normally everything is fine. but whenever I add “Landscape Auto Material” to my project and apply it to any landscape it fails during Packaging the game, I was trying for window 64bit build.
is it a landscape auto material problem or the problem is in my pc??
last night I tried the same thing in my mac, and build a version for mac. that was fine. no error.

Try deleting the LAM maps or any other LAM sub-folder (in your projects content folder) you don’t need. It’s a sloppy way to solve the problem, but it worked for me.
