Terrain cover statics - other ay to create it?

Hi all,

i have a simple question to the 3D Modeling artists about how to create terrain cover that's looking better at all and not this straight flat plainstatics.

I was thinking about if i can create terrain covers out of pure preopt files (as blueprint) from the navmesh process?

Excample what i mean:

I navmesh an area of a map, this navmesh and the preopt's files get loaded into 3ds and the 3d artist can create out of this files better looking terrain covers that fit better with the original terrain without spending time to create it by yourself?

Thanks in advance,

FJ
