Hey Community,
I made a collection of Unity Terrains, some are selfmade, some are from Google Image search…
I will expand it soon and will add details…
Unity Islands
You have terrains you would like to add? Just tell me and i will add them 
This is just for showcase and wont we sold anytime

EDIT: sorry guys link was wrong :S
The textures could use some work, also they could have been smoothed out more. Some of them were really good, others not so much.
Thanks for the critics 
I use the default unity textures :S
Updated the player with some trees 
Working on some procedural terrains with world machine 
great !!!
you could also think at a random generation of islands
