That's the groundcover you have on your terrain types. When you copied your template map across, you either didn't copy this folder, or you didn't rename the folder locations properly. If you load up the console (I think it is the ~ button), this will show you which materials are not working. You can then go and either fix them there, or copy the correct folders across.
