Missing terrain materials when creating my new map

Hello there,

I was creating a new map using some tools, copied over the East Coast USA assets into my new map, deleted everything except spawn points and the sun and water, and this. I was wondering how I go and fix this, it's been a while since I have made maps for Beam. So if anybody can tell me how to fix this, I would really appreciate it.

It would also be helpful if I decide to create even more maps in the future.

Kindest regards,
Mr. Embracer

 

It seems you are missing the texture maps.
This should help:
