Hi,
I assume you mean, can you use say, lush and desert terrain on the same map.
The short answer is no. We would like to offer many more texture options, but it's oddly not quite as straight forward as you'd think.
It however is a much requested feature, so I imagine we'll be looking at it at some point. In the meantime, you can of course use different terrains in different levels.
